Hello,
I am in France and I cannot connect to GSM networks with my Edgebox-ESP100.
Everything is OK in LTE mode and my multioperator SIM card is ok in another modem in GSM mode.
I suppose it’s because of the GSM bands not being enabled in the A7670G chip.
I’m trying to modify the bands according to the documentation :
AT+CNBP=0XFFFFFFFF7FFFFFFF
OK
Unfortunately only a few bands are activated, I cannot activate all the bands of the A7670G chip:
AT+CNBP?
+CNBP: 0X0000000000280180,0X000001E2080800DF,0X0002
However, this chip is well designed for a GLOBAL region (G model).
Any ideas ?
