ValueError: invalid join data rate 3 Lopy LORAWAN

@jclo13 Deepsleep wakeup is a reset. So before going to deepsleep, you have to save the LORA state tio nvram and restore it after that from nvram. No need to run join again, because the credentials are still valid. Actually, once a device has being joind and the credentials are established, there is no need to join with again, at least with OTAA.

The problem you see may be caused by replaying packet numbers. You can verify that in the TTN console by unchecking the box "frame counter checks" in the devices settings. For testing this is an acceptable setting.

@Xykon yes, I am using lora.nvram_save() and then lora.nvram_restore().

@robert-hh, I unchecked the box mentioned and it worked, thank you. but you mention for testing, how can I solve the problem if I want to check the counter frame?

@jclo13 You can reset the counter in the TTN console to 0. Then the next message from the mote will synchronize the counter to a common value.

[robert-hh]

@malachib There is a PR for that to fix the issue (https://github.com/pycom/pycom-micropython-sigfox/pull/183), but that did not make it into the master branch or development branch yet.
