@pierrot10 Yes, you can use a FTDI cable, or a RasPi. YOu need to connect Tx, Rx and GND. Verify that the output voltage of the adaper is set to 3.3V, since ESP32 input are not 5V tolerant.

@livius Many thanks i'm waiting to receive the first lot of FiPy and start the NB-IOT journey

@livius Did a quick try. Got the following error: Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/flash/lib/urequests.py", line 141, in urlopen File "/flash/lib/urequests.py", line 38, in __init__ OSError: -32512 Will look more into it later, but as fare as I can Google it might have something to do with the antenna transmission.

Hello, i fllied a ticked : https://github.com/pycom/pycom-micropython/issues/47 Testing with firmware 0.9.7 don't fix. I don't use garbage collector, and my code use only one thread. The error only occur after client connected in the message listen loop, and if i use the console. But server still running and working after error. I suspect interference with console or my own network because error occur only every 30 or 40 seconds Hope that it will be fixed by next Release ;-) Cheers
