@crumble said in Lopy freezes after 6 - 12 hours: I do not understand why pycom does not declare the 1.20 branch as stable. It fixed so many errors for me that I like to see it as the stable branch. Maybe they want to deploy it together with some cloud changes. But 23 will be the better number for this ;) Features are still being worked on and improved. Even more stability cant hurt :D

@paul-thornton Thanks for the response and information to this important thread. Just to let you know, the blocking and unstable lte.init()/deinit() behavior is forcing me to consider totally switching platforms, and abandoning Pycom. I am running the newest modem firmware.

@crumble Thanks! ... it did the trick

@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.

giving up for now and hoping for the FiPy
