Hi,
Modem : EM7421
Firmware : SWI9X50C_01.14.03.00 b06bd3 jenkins 2020/09/23 10:53:35
I’m facing an issue with disabling Band 8 on my EM7421 modem using AT commands. Here’s a summary of the situation:
I have the following mask table for disabling Band 8:
0002000004400000, 000007A088080045, 0000000000000000, 0000000000000000, 0000000000000000, 0000000000000000
I created a new mask profile with the command:
AT!BAND=10, "Sans_B8", 0002000004400000, 000007A088080045, 0000000000000000, 0000000000000000, 0000000000000000, 0000000000000000
However, when I apply this profile with the command AT!BAND=10
, the modem defaults to profile 00 without displaying any error message.
I tried selecting another profile, and it works.
I also attempted to change an existing band (03), but I encountered the same initial problem.
Even in developer mode, I couldn’t resolve the issue.
Do you have any ideas or suggestions to help me solve this issue?
Thanks in advance for your help!
Best regards,
