  @jsh in my case I don't need to worry about power. I am also more interested that the device is on and monitoring. The devices are on diesel pumps and they need to stop and start based on water level. So the pycom power draw is a minor component. 12V system needs to keep things powered on so Solar is present to keep eveything charged. But your right WDT, should be only a last resort, not a requirement to get a system running reliably all. (though a necessary last resort)

  @paddy Agreed. The lack of stability needs to be addressed!

  @jadowdl You do not need an expansion board. Almost any USB/UART bridge and a few cables will do. You just have ot take care that the USB/UART bridge can supply 5V while the UART signals are at 3.3v. If you already have a REPL prompt through USB, then you are almost set. The only additional step for upload is to connect P2 to GND and pzsh reset. About Pin numbers, look here:https://docs.pycom.io/chapter/datasheets/development/gpy.html

  @andy_n 1nce only supplies to commercial customers. So be sure to include the company registration. I also tried to contact T-Com for test cards. No reponse so far. As a company, you can buy Nb-IOT packages at the Telekom Shop or Business Customers sales. The smallest package is 25 SIMs with 500k data volume each, active for 6 months (https://www.telekom.com/en/media/media-information/archive/first-narrowband-iot-service-packages-launched-in-germany-497494). Sounds not overly attractive.

  @xykon I did that more than a week ago, but didn't get a response (PYCSD-271). I figured my chances would be better on the forum, and it turns out they are ;) . You are welcome to help me here or via the support portal, I have no preference in that respect.

  The most pressing item is just how do I identify the client that is connecting to the GPy over BLE? Typically a BLE radio will give a MAC address and a connection handle to be able to manage the connection. I am not seeing anything in the docs that addresses this.

  @wgtthompson I found this to be the case as well. Just hung at the lte instantiation until i started resetting it after declaring it even if using the same carrier as before.

  @tanmay07 Got it thanks a ton! I was also looking for another scenario where I do not have to use this. Suppose I configure my device to be on a deepsleep it consumes about 25uA current. But I want it to wake up on certain levels of voltage from my sensors on analog pins. Is it possible to do this using:- machine.pin_deepsleep_wakeup(pins, mode, enable_pull) ?? Because I believe this function can only wakeup the decice from deep sleep if the specidied pins goes high or low.This can be used for specific voltage levels on analog pins right?

  @jmarcelino today i was able to add the code: import time import machine from network import LTE i=True while i==True: print('nomal mode 15sec') time.sleep(15) i = False lte = LTE() lte.deinit() print('deepsleep mode 15sec') machine.deepsleep(15000) but it just runs the error: >>> Running o:\Benutzerablagen\Nellis\Pycom GPY\ProjektTest\main.py >>> >>> >>> >>> nomal mode 15sec ╝Traceback (most recent call last): File "<stdin>", line 16, in <module> OSError: the requested operation failed ╝> MicroPython v1.8.6-849-83e2f7f on 2018-03-19; GPy with ESP32 Type "help()" for more information. Is there an other solution i could try?
