I have the RAK2560 Wisnode sensor HUB and im trying to send data via NB but some SIM errors appears:
- Using the AT command AT+CREG? it returns +CREG:0,2
- With AT+QSIMSTAT it returns +CME ERROR: 100 and i don’t really know what it means.
I’m powering the sensor HUB with his 12V dc adapter. Its necessary to suply with the external batteries?
Thanks in advance.
