I have the board Sodaq Sara R410M. I have two differents cards (vodafone, Anritsou)
When i make scanning (AT+COPS=?) the one card find 3 networks but the other 2 networks…
i confirm that several times. Why the sim card influence the scanning??
The only thing that is different is that i define different apn (AT+CGDCONT=1,…) for each card.
Does anyone knows why happens this??
Did you turn off some bands in one module?
AT+UBANDMASK? will return the bitmask.
More info about ubandmask see:
I use the same module . I just change the sim Card to the same module. The UBANDMASK i think is the default which is for all bands.
The default is indeed all bands.
Can you check if you use the latest firmware on both boards?
I will also contact ublox about this issue, maybe they have an explanation.
