@jmarcelino exactly if someone have acces to device it can break it in really simpler manner than do some supported by some device reset features ;-) @lawrence Think about as @jmarcelino show sample, hammer, drill i can add more e.g.: water, remove power source, electric shock, put into metal case...

@robert-hh Thanks a lot Robert and Livius! I saw indeed the PWM example in the Micropython docs to dim a led.

Application shared key is between your sensor and your server normally. Provider would only need the network key.

@jmarcelino Cables are really very short. Can't be shorter... Baud rate is 100000. I tried different baud rates but this value seems to be the correct. I will try the pullup resistors today

Hi assia, did you solve the problem ?

@constantinos As you can see above he use already very slow long range: bandwidth=LoRa.BW_125KHZ,coding_rate=LoRa.CODING_4_8,sf=12

@berpast Drill a suitable hole at the opposite side, or wherever it fits, given the antenna and it cable length.

@PiAir Very nice, thanks for sharing!

@Eric24 It is through the ULP. I'm not sure how Pycom will work with the ULP in Python, very curious to see.

Correction to my previous comment, the default Marvin code contains the send_LoRa_Command("mac set adr on"); command. So indeed it switches on ADR on purpose and not by default.

@PiAir Thank you for sharing this

@robert-hh Oke, will make a test program. When USB is connected it indeed has a higher voltage :'). That was another mistake/issue I had :). Thanks a lot, again!

@jmarcelino Unfortunately, the procedure posted here https://github.com/pycom/pycom-micropython-sigfox/issues/5 doesn't work. I' ve followed these steps: Change bootloader (1536 -> 1024) make BOARD=WIPY TARGET=boot make BOARD=WIPY TARGET=app make BOARD=WIPY flash everything work and now with Filezilla I can upload file with size > 1MB After I create a new image edited the frozen file _boot.py with a print("Hello World") make BOARD=WIPY TARGET=boot make BOARD=WIPY TARGET=app with Filezilla I copy appimg.bin in /flash/sys/ reset the board (with the physical button ) firmware doesn't change Instead if I execute: make BOARD=WIPY flash, the firmware changes. So I think that "the updater task" doesn't start on reset. EDIT: I notice that the file appimg.bin uploaded with Filezilla disappears immediately, before reset.

@robert-hh Ok thank you (I use the good pin and all of your code).
