Wireless Modules / Re: inAir9, is J1 always here ?
« on: October 08, 2015, 02:44:12 PM »
Very sorry about this. Not sure how that slipped though our test. All inAir modules are connected to a tested that tests the transmit and receive signal strength. It will not pass if this jumper is not made. Maybe you got one of the very first modules when we released this board - before we had our current tester?

At delivery, the RF Switch is always made.

  • On the newer boards, there is a solder jumper on the back of the board. It is clearly marked J1, and is made by default. So, by default, jumper J1 is made, and it powers the RF switch.
  • The older boards don't have a solder jumper(J1) for the RF switch, and it is always powered.

The RF Switch was added to newer boards for applications that need to go into very low power mode. The RF switch only consumes a couple of uA power, but for very low power applications, that is not desirable. So, to save the maximum amount of power, solder jumper J1 can be opened, allowing the RF switch only to be powered when transmitting or receiving.

Hi, sorry for long delay. Been very busy getting required hardware manufactured. We now have a new base board, the PT4NZ. It can take 4 x iMod modules, like LoRa SX1276, Bluetooth, RS232, RS485, Mosfet, Relay, Opto Input... The inAir boards(433, 868 and 915MHz LoRa modules) are LoRa modules. So, you can have the 1 LoRa module on the STM32 board, and 4 additional ones on the PT4NZ board. So, a total of 5 boards. Generally 1 will be a dedicated transmitter, and the rest for receive. So, 1 x Transmit and 4 x Receive. It will require 2 antennas. One for the transmitter, and the 4 receive channels combined via a splitter.

I attached a photo showing a Gateway with 1 x Transmit, 3 x Receive, and a 6-28V switch mode power iMod, the pm35SS-5.

SBC66EC & SBC66ECL / Re: === New V2.03 Beta Firmware Available ===

Hi Muarice

Will look at this a bit later this week. Are there any other tags you need supported?

Also, you don't have to spend $500 on a compiler license. The free MPLAB XC16 compiler works just fine. It just creates code a bit larger.

Basically to prevent to !Def from being displays, you have to us a matching firmware and matching web page files.

When performing these tests were you keeping the modules within the EC and FCC limitations? (I know the modules are not yet certified, but I would like to understand how "real" is the result and how will this be altered after a future certification)
Yes, we did them with the inAir9 module(920MHz), which is only 25mW(14dBm). This is within the legal limits for that frequency. The new inAir9B will be able to go up to 100mW(20dBm)

Are we talking about weeks or months before the module will be certified?
Currently nothing scheduled or planed, so will be many months till/if we get any certification.

3) Boards were shipped to us yesterday. Should be available next week. Please send me an email again next week.

What will be the price for the gateway? Can I please have the datasheet for it by email?
Board for gateway was also shipped to us yesterday. But, the software will take couple of weeks. Will be making it publicly available, so first bete version should hopefully be available within 2 weeks. Price should be around USD80 to USD100 for Gateway with 4 Lora Modems.

I don't want them to transmit in the same time. I wanted to know if the module can support a set of rules according to which, at a certain point, the module will switch from WiFi to Bluetooth or from LoRa to Wifi, for example.
Yes, this will be no problem.

Do you think it is possible to have more details and a price for this, by email? Was there an accelerometer used as well or just a GPS module?
Only GPS, no accelerometer. Please send me an email for details.

Sorry but my question was a little bit confusing. My point was: do you sell the modules already preset for 868 MHz or 915 MHz (as two different modules), or they come as universals (as one single module) and you provide a GUI that will allow us to set the frequency? 
The inAir9 module works for 868 and 915, and is configured by software for required frequency.

What is your production capacity for the inAir9 modules and where are they manufactured?
Most of our production is done by a company in Taiwan, but we also use a different company in China some times. We can get them to manufacture/test many 1000 modules per week if required. Will however have lead time of 5-8 weeks for larger orders (500+). These modules are becoming very popular, and we will be increasing our stock.

Can you please tell me what is the price for the  NZ32-ST1L board and if you have any available at this point?
Have a couple of 100 available. Price is USD24. Will however be releasing a much cheaper version with smaller CPU (STM32070C8) and no battery charging circuitry for below USD15.

"During your tests, what was the real maximum range you achieved with inAir9?"
Range depends on the Bandwidth and Scalling Factor setting of the LoRa modem. The lower the baud rate, the higher the sensitivity, and further the range. We did many test with the module, but our area is very built up and hilly, so need to still find a flat area to do proper tests. One of our customers got about 25 to 30km in Victoria Australia, which is very flat. We easily got 4km in the city using low power (14dBm) inAir9 module and 2dBm whip antenna.

"Do you have CE certification for 868 and FCC certification for 915?"
Currently none, but very big demand for this module, and will soon be looking into this

"Is there a development kit available?"
Should have development kit in about 2 weeks time. Consists out of a base board with OLED display and buttons. The STM32 and inAir9(LoRa) modules plug into this base board.

4)
Quote
"Do you also have a LoRa gateway?"
Is getting delivered to us at same time as development kit. Will be base board with STM32 processor and 4 x inAir LoRa modules(433, 868 or 915MHz). Will have a USB port that for communicating with LoRa modules, and connect to CPU like Raspberry Pi. First implementation will configure 1 of the LoRa modules as a transmitter, and the other 3 as receivers.

You mentioned that the NZ32-ST1L boards have 3 iMod ports. This means that if WiFi, Bluetooth and SX1276 are connected in the same time, the board has the option to switch between them?"
This should be possible. Not sure how they will work if all are transmitting at the same time, the WiFi and Bluetooth have some frequency, so might interfere with each other. Just added Bluetooth module short while ago. Will be adding Bluetooth V4 soon too. modtronix.com/in6bt.html

Quote
"Can an accelerometer or a GPS be added to the NZ32-ST1L board?"
We have implemented this for a customer, and added a 1.0mm GPS connector to a base board that fits onto the NZ32-ST1L board. It takes a ADH Tech GPS module.

Quote
"For the inAir9 module, both 868 and 915 are available? Or there is one single module and this setting is manually done?"
There is a single module for both. We were also surprised by this, but Semtech confirmed multiple times this is the way LoRa works. Contact Semtech, or download their LoRa reference design, and you will see it is identical for 868 and 915MHz. See Semtech SX1276RF1KAS and SX1276RF1IAS reference designs.

"For the current version of this module you already have installed an RF shield or it is still coming without it?"
Current inAir9 modules are without RF Shield. All new inAir9 modules will have RF shield (about 4-5 weeks away). The inAir4(434) and inAir9B(915MHz high power 20dBm) will only be available with shields. After current inAir9 stock is sold, all modules will have a shield.

"The module can have a PCB antenna?"
Currently none with PCB antenna. We will however soon be adding very small, 5cm long antennas to our site.

SBC66EC & SBC66ECL / Re: Displaying Analog inputs
« on: March 01, 2015, 05:37:41 PM »
Hello Atif

Sorry for long delay, but this required quite a bit more code than expected. It is nearly done. It will now be possible to configure each port (via web page, UDP or USB) to be Digitial input/Output, PWM output or ADC(analog) input. You will need to configure as analog input. For example, to configure port 1 as an analog input:
Code: [Select]
c1=an
Will update the Webserver Commands with the new commands.

The value of any port can be obtained via the "i" tag. So, to get value of port 1, use following tag:
Code: [Select]
#i1
Will update the Webserver Tags with the new commands.

To use this on your web page, simply add "~#i1~" to your web page, and the value of the analog input will be displayed.

I fixed the link on the old site. You can now download the version for windows 7/8:

Wireless Modules / Re: inAir8 when? + range testing
« on: February 24, 2015, 07:53:05 PM »
Hello Lawrence, sorry for delay! Yes, the 868 MHz modules are ready. It turns out, the circuit for 868MHz and 915MHz is identical. See Semtech reference designs SX1276RF1IAS and SX1276RF1KAS, the 868 and 915MHz circuits are identical. I thought it might be a mistake in the circuit (BOM), but Semtech confirmed our (their) circuit is optimized for 868 and 915MHz.  This has been confirmed by Semtech, who reviewed our design. We have also tested 868 MHz on the inAir9, and works fine.

Would be great if you are willing to do range tests.  I can send some free samples if you agree to create a small forum post with results. Please provide your courier account and shipping details. As mentioned in previous post, many of the cheap SX1276 modules available have terrible ranges, use 2 layer boards (not RF/impedance optimized), and inferior components. We have a 4 layer PCB, approved by Semtech engineers, and only very high quality components.

SBC66EC & SBC66ECL / Re: Lost the main page
« on: February 02, 2015, 12:24:17 AM »
Hello Atif, the display you are seeing is because the firmware and web pages do not match. You have to ensure that you upload the web pages that were created for the specific firmware you have on your board. Did you update the firmware on your board? And, please specify exactly where you got the webpages from.

« on: February 01, 2015, 08:53:21 PM »
Hello Atif, did you program the board using the "Netcruzer USB Bootloader", or a PIC programmer (like PICKit or ICD)?

1) If you used the "Netcruzer USB Bootloader", your bootloader will still be on the board, and you can update the web pages as described here:
www.netcruzer.com/nz/doc/proj_webserver_webpages_update

2) If you used a PIC programmer, you will have to restore the firmware on your board also using a PIC programmer. Once that is done, you can restore the web pages as detailed in 1 above. For details on restoring the firmware, see:
www.netcruzer.com/nz/doc/update_firmware/

Hello Atif

You can of course add any dynamic content to the source code by following the steps described in the <Stack API><HTTP2 Server><Features><Dynamic Variables> section of the "Microchip TCP/IP stack documentation".

You can download the "Microchip TCP/IP stack documentation" in pdf format, or in Windows Help File format (*.chm).

Hello Atif

I will send you the HTML code for a demo web page that displays the Analog values for 3 input port. On your HTML page, you use tags for displaying dynamic values. For details, see:
http://netcruzer.com/project-webserver-tags.html

I will try to get the Analog input tags completed by the end of this week. This will enable you to display analog input value by simply adding a "i" input tag to your HTML web page.

General Questions / Re: inAir8 when exactly in 2015.
« on: December 18, 2014, 01:08:52 PM »
Hi, sorry for late reply! We hope to have it available February/March 2015. Could you use the 915MHz version for testing so long? They will be identical, except for the circuit will be for 868Mhz. We are looking at getting CE approval, but initial version will not have it. I am quite sure it will pass, seeing that we designed these boards with assistance from Semtech Engineers, and made several changes to prototype for low radiation. All versions from next year will also have a metal RF shield covering all RF components.

SBC66EC & SBC66ECL / Re: SBC66ECL with no UART demo code? No thanks!
« on: December 08, 2014, 09:41:19 PM »
Hi, I have uploaded the the netcruzer project, v2.03 to GitHub. The UART is now supported, and working. For an example of how to use the UART, see the demo projects in the "src/demos/uart" folder. It is here on GitHub:
https://github.com/modtronix-com/netcruzer-src/tree/master/src/demos/uart

You can build these demos, and program your SBC66 board with it.
