  @Fred @bucknall Do you have any expected shipping date for Kickstarter backers for FiPy (and Pysense, and Pytrack) ?

  @Eric24 For what it's worth, I repeated the test with a 10nF capacitor and a test code, which switches the output value high/low. To my surprise, the figure looks as if the capacitor is charged with a constant current. The calculation gave a current of ~47 µA, which matches the 1.53V seen across the 33k resistor.

  @antonms At the C level you can do I2S input using the (very new and largely untested) ESP-IDF drivers but I think a Python layer is very far away considering the amount of data, speed and DMA access required.

  Hi @Eric24, I might be incorrect on this but I believe that when you wake from deep sleep, the device should start up with the radios turned off. Regardless, you should be able to configure the radios to remain off at power on by tweaking and building the firmware yourself. I'll make this suggestion to have an option to disable radios baked into our official Firmware itself.

  @Eric24 said in What is the maximum size (capacity) supported for the SD card?: It is 32GB - but as described somwhere on the forum it will be increased in the future firmware releases

  @Eric24 we will update the data sheets with more detailed info about operating ranges soon, but in the meantime, from 2.7 to 3.6 V is the recommended range. Same during deep sleep.

  @robert-hh Thanks for that specific detail. It is especially interesting to have a mode for both. I was not aware of that to be possible. Currently I got my LoPy connected (to my other wlan). It was a failure to get an IP address in the first wlan. I may have some issues with that wlan. Now I have setup a dns name in my lan and can reach the gateway by it's name. The next step is to get it registering with TTN :-)

  @Vercellotti The pyb module exists for PyBoard in the micropython.org family of ports, not for the Pycom family of boards. Since the Pycom software is derived from these, it is mentioned still at some places in the docs. The module machine is to be used instead.

  @pmulvey I do not see a reason for the difference, but I execute the piece of code for setting up the network interface from main.py. Actually it is in a separate file, let's call it "setup_wifi.py", and I have a statement import setup_wifi in main.py. It is usual practice to make main.py simple and to put you application code into separate files, which are then imported in main.py, eventually enclosed in a try/except clause. That way the device comes up in a stable state, even if you code flags errors.

  If you are looking for simple REPL through telnet I can recommend you to check out my Python script: link Easiest way to get started :) If you want to write scripts for your device, like main.py (a.k.a. modules) then you can do so in your favorite code editor and upload through ftp.

  Ill be testing with a neo-6 GPS module soon link. LoRa will be used to send the coordinates. (we will also try something like Geo-LoRa or trilateration with LoRa, but don't expect the accuracy to be anywhere near that of GNSS solutions). The metal is probably going to block the signal in your case, but ill let you know how sensitive it is.

  Hi @jasonriedy There's nothing in the way of tooling at the moment but I'll have a chat with the team to see about putting out a benchmark script to verify power efficiency. Will let you know when I've heard back!

  @farshadfirouzi Cat M1 has a much higher bandwidth and no duty cycle restrictions as it operates in a private band so I think it should work, but of course you'll pay a subscription to your carrier. Also the peak current consumption should be higher than LoRa so that's something to keep in mind if powering from batteries. If you really have an application using 10,000 nodes and consuming 40GB a day I can imagine Verizon would want to talk to you but really I can't say anything about that. Here in the UK it would definitely open some doors. You will need to work with your carrier to supply a base station because, unlike LoRa, they own the frequency spectrum.

  Hi @smssms You could try a 2000 mAh LiPo Battery - https://shop.pimoroni.com/products/lipo-battery-pack I'm sure you can find these cheaper/closer to where you are located but I know these work well as I've used them before from this specific supplier.
