Known bug in 0xC0

There is a known bug in the version 0xC0 and 0xBF, which is not present in the previous versions.

If you use DeepSleep before you Join the LoRaWAN network, it will not be able to join the network. This is only with deep sleep, and only when used before LoRaWAN_Join. Instead of deep sleep (modeDeepSleep), you can use regular sleep (modeSleep), which will take more current in sleep.
