Signed type used to represent dev-addr in ABP tuple?
See also the TTN forum.
When using lora.join with ABP and values larger than 0x7FFFFFFF are used for devaddr (e.g. 0x80000000 and up) then the lora.join raises a "OverflowError: overflow converting long int to machine word"
Thanks for the report. The fix will be available on the next release.
