R412 & Hologram CME Error

SARA AFF
1

I’m trying to prepare a prototype using a SARA AFF R412M and a SIM card from Hologram, and am running into issues.
I’m following their getting started guide that’s written for the R410 and making adaptations per the ublox manual.

The first issue is that I’m not able to modify the ubandmask. Executing the command results in an error:
AT+UBANDMASK=0,275063445663,1,185538719
ERROR

On top of that I’m able to establish a TCP connection to Hologram, but encounter a CME error when trying to send a message:
AT+USOCR=6
+USOCR: 0
OK
AT+USOCO=0,"cloudsocket.hologram.io",9999
OK
AT+UDCONF=1,1
OK
AT+USOWR=0,82,"7b*****************************************************************************7d"
+CME ERROR: Operation not allowed

What am I missing?

Hi @noamt,

Before you can change the bandmask you need to set the mno profile.

The difference between the R410 and R412 is when you make a connection with the R412 you need to have the battery connected. The reason is the current consumption of the 2G fallback. Did you have the battery connected?

Best regards,
Jan

Yes, sorry for not including this in the original post.
My mno profile is set 100 and the battery is connected

This is a test command, it’s not required to make a connection.
