@Bernal-R This issue has been solved in Pymakr v1.4.2, which was released today.

@dmnk Sorry dominik, i have emergency on other projet and cannot do some test with my lopy4. In fact, as i previously said i work with sigfox on my company product. We send setting via downlink on our device to start them when necessary. For a 10K fleet device, 95% of them have receive downlink after 3 downlink (and aprox 50% one first downlink), so definitly for me downlink is more weak than uplink. As i understood the ohter post from xorlover and answer from seb, it's sigfox FSK ptp that is not yet present in firmware.

The file is called main.py, and it always was, so i don't think it can be it. I have a project created, and all the file are inside, i can access it through windows explorer as well, for the code, i can explain it, and post a screen about it if you want. I use the internal RTC (even if i can't update the time, i can initialise it and do something when X date is reached, even if there is no save if the system is not alimented anymore, that's enough for me) i also use an analogic pin for taking a battery pourcentage, and i send a message when a pin receive something. If you really want all the code here it is from network import Sigfox from machine import Pin from machine import RTC import pycom import socket import machine import time class ComSigFox: msg = "" localisation = "" socket = "" Etat = "" tailleManquante = 0 Compteur = 0 def __init__(self): # Initialise SigFox en Europe (RCZ1) localisation = Sigfox(mode=Sigfox.SIGFOX, rcz=Sigfox.RCZ1) def sendMsg(self, paramMsg): pycom.rgbled(0x007f00) # vert # Créer un socket SigFox s = socket.socket(socket.AF_SIGFOX, socket.SOCK_RAW) # Bloque le socket s.setblocking(True) # Configure le socket en Uplink seulement (False / True) s.setsockopt(socket.SOL_SIGFOX, socket.SO_RX, False) msg = paramMsg msg += " %" if((len(msg) ) < 5 ): # Si le message fait en dessous de 5 caractères tailleManquante = 5 -

It just happened to me too :-( Yesterday it worked, and today it doesn't.

@jmarcelino how do you make a denit() of LoRa or Sigfox please ?

@jmarcelino even in outdoors (completely flat field) the reads are erractic. Could you confirm me that the class of the tranceiver in FiPy is 0U??

@jmarcelino said in Sigfox RC4 Freezing after 1 msg: time.sleep(20) Works like a charm. Thanks a lot. The documentation is a bit misguiding here, it says : "there must a minimum of a 20s delay after resetting to the default macro-channel. Our API takes care of this for i in range(1, 100): # send something s.send('Hello ' + str(i)) There will be a 20 second delay after every 2 packets" In fact, there should be a delay added between 2 packets. Maybe a suggestion for modification of the doc. Anyway, thanks a lot for correcting me ! All the best.

When I started I first read this tutorial to understand the Python language. Not everything is available in Micropython, but you get the concept: https://docs.python.org/3/tutorial/ I looked up details uniqe to Micropython here when I found something from Python that was not working: http://docs.micropython.org/en/latest/pyboard/ For Pycom functionality documentation and examples are available here: https://docs.pycom.io/ Johan

@pmb_nl i have the same problem, do You have some solution about it? Thanks

@seb Just tried 1.15.0.b1 and the first 2 tries where successful. Thanks!

Hi @misterlisty You will have access to more details and to the coverage API once you register your device (follow the guide on pycom.io and register through backend.sigfox.com/activate). Aurelien

@xykon Great it works fine now, thanks a lot for your help.

I just made a mistake with the pins, the one I needed to not change were G12, G13 and G14 and not like mentionned above. I'm still interested if I could use those Pins for input and then somehow deinit so that the communication still works.

@pymiom @mbartecki I got the new public firmware supporting Sigfox, by updating the device this morning! Enjoy guys :) Thank you @jmarcelino
