  @techykermit said in So GPy is phase-out now what?: The new hardware will work with the old code after some pin adjustments etc. Which means: expect major porting effort. I guess the new hardware is what they announce as the F01 series, for which there is an offer for a development pack. The new hardware looks promising on paper, using the STM F7xx as hardware and Murata radio devices. Let's see how Pycom manages the firmware.

  @Cédric-Antenen We have roughly 200 lines of code on both sides Gpy (Python) and update server (C). Update speed depends on you files' size, signal quality and round trip time. We have seen about 1...4 s per data block (data transmitted and acknowledge received). Sorry, I can't share the code here, since solving such problems is what I do for a living :)

  @Mohsen-Paryavi did you have any luck getting this to work? I'm interest in doing the same, using the Gpy as a LTE Cat-m1 hotspot. Allowing a phone to wifi-call beyond LTE coverage.

  so i dove into this a bit deeper and beleive this issue has to do with LTE.deinit not functioning properly in deepsleep when using WLAN. It's hard to explain as the correct factors which are unknown right now have to happen to cause this issue as it's not all the time.

  Status Update (12 May 2022) - I was never able to get PyGate#2 to communicate on it's serial port. The supplier (PiShop.us) was very prompt in responding to my issue. Their technical support team stayed in touch and sent me a replacement unit.

  Hello Matt, Sorry for the delay and the auto-message for the last time. GPy, supports both CAT M1 and NB1. But to clarify not the M1. You may refer here for the detailed specs or here to have some concrete examples. Have a good one, Yusuf

  Today I have measured the power consumption. The power consumption is about 265 mA. So for my application I will use a powersupply with 300 mA.

  @hakan-sanli I noticed you have not received any reply yet, a pattern I think relates to the fact that Pycom's primary focus is on their backend service offering, hardware is just a tool to get there, hence they discourage non Pycom firmware development. We have just started out on the same road, but still cannot get to flash WiPy or FiPy devices reliably using the PySense and PyTrack boards. Have connected a switch to EN pin and tried 5 different USB adapters, 4 different types. No luck getting any output But (using PySense or PyTrack) the devices connect to the dev platform and can be flashed, upgraded and operated. Any suggestions?

  @Matt-Xu-0 Make sure you check the box for flash erase before you upgrade. Also, make sure you release GPIO 0 to get out of bootloader mode.

  @kjm that's a bit esoteric for my current knowledge levels. I would have assumed that the "flash" is fragile regardless of language? Also, I'd be curious how you manage to stick to RTC RAM only. TBH, my gripe is with the docs not being updating properly when Pycom/Micropython API changes are made. I could forgive it if they references the external Micropython docs for the latter. I'm not even annoyed that I have to recreate the filesystem so often, given the frequency that I make changes and re-upload a project. Never too late to learn a new language, trouble is there always so many to choose from.

  Maybe it is another problem. I did what the doc said. Holding the safe boot button and restart the device, VS code cannot connect to the device. It just showing 'Connecting to COM3...'. In my device manager, I can see the device is "Port(COM and LPT) USB Serial Device (COM3)". (Something like that since my os is Chinese). The LED flashes blue every 5 seconds (heartbeat perhaps). Thank you!

  @jcaron This is what I am referring to: machine.unique_id() # return the 6-byte unique id of the board (the LoPy's WiFi MAC address) [https://docs.pycom.io/firmwareapi/pycom/machine/#machineunique_id] -the question is how that id is formated, and if all parts are unique, or just parts.

  I don't use the GPy for sending whole files, but basically as a device to send data in real time every few minutes. I have an Arduino connected to a GPy via serial. The Arduino sends data strings to the GPy. The GPy sends the data to my database at the end. I have to tell you though, that sending data via LTE-M didn't work reliably for me till I took some certain measures. Problem 1: The GPy consistently stopped working for me after a short while (every few days), because of Guru Meditation Errors, where the GPy often completely froze. It just couldn't recover by itself. That's why I've used my Arduino also as an external Watchdog, resetting the GPy with the Arduino. These Guru Meditation Errors seem to come up pretty often while using it to transmit data (LTE-M). Problem 2: Sometimes the GPy also thinks it has a data connection, while it is not the case. Using the Reset pin on the GPy doesn't help in this case. That's why I also had to implement a P-Channel Mosfet, which cuts the power off from the GPy. This power cycle helps with the problem in my experience. The features of Pycom hardware are wonderful, if you are interested in getting your data onto a server, but you have to take some measures to make it work reliably. I wish you good luck with your project!

  @goldfishalpha Found a snippet somewhere about that and it is now a religious expectation to select both, it should just enable them by defult.
