I am testing several Quectel’s modems:
- BC95-G (Revision:BC95GJBR02A03)
- BG77 (Revision: BG77LAR02A04)
- BG96 (Revision: BG96MAR02A07M1G)
With all of them, I successfully connect in eMTC mode (LTE-M/CAT-M), but the, with NB-IoT one it just works with the BG96.
My lab setup:
- PLMN = 00101
- LTE Band 3
- NB-IoT InBand mode
- APN = internet
For connecting as CIoT, the command “AT+COPS=1,2,“00101”,9” is used.
Any suggestion what to verify what is going on and to get also the other modems attached?
