@arno Unfortunately the deepsleep shield does not have any such functionality

@sympatron ACK, so my tendency is to close that attempt.

@livius I made a version in which you can control the join behaviour. It is just a handful of code lines. You'll find it here: https://github.com/robert-hh/pycom-micropython-sigfox/tree/otaa I added an optional parameter to join. Edit: While testing it came again to my mind to me that you can achieve the same thing with the standard SW: step1: do an otaa join step2: take the parameters from the web console, use them as ABP parameters and use ABP join then with just the single frequency in the list of channels. If you then save the state to nvs_ram, you do not have to call join again. The keys will be restored by nvs_restore(), which you must call anyhow to set the counters.

@robert-hh That is strange. I had a look at the pulses coming from the Launchpad and they look fine. I'll do more testing later. [image: 1490646885295-ds2_quickprint10-resized.png]
