Sodaq_RN2483 - initOTA returns true but send() gives errors code 7

Hi,

I have been testing the Sodaq_RN2483 library and I have run into a funny situation whereby the LoRaBee.initOTA returns with true but a subsequent call to LoRaBee.send() returns a code 7 which according to the docs means “not connected”… anyone seen this before ?

Thanks,
Serge
