Hello,
After I have updated the module EG912Y from version EG912YEUAAR01A08M16 to the version EG912YEUAAR01A11M16 I find a problem with the command at+cmgf=1 when the CMUX is enabled.
It seems that it’s impossible to set the format of the short messages to TEXT mode.
Please, see the file attached.
My comment:
at line 109 CMUX started:
[2021-12-29 14:09:29.322] AT+CMUX=0,0,5,1500,10,3,30,10,2
at line 139 I set SMS text mode (on CMUX channel 1)
[2021-12-29 14:09:29.460] AT+CMGF=1

at line 212 I check the state of CMGF and it is 0=PDU (Why???)
[2021-12-29 14:09:30.137] AT+CMGF?

at line 231 the command AT+CMGL=“ALL” fails… i think because SMS is not set as text mode
[2021-12-29 14:09:30.171] AT+CMGL=“ALL”
[2021-12-29 14:09:30.202]
[2021-12-29 14:09:30.202] MDM1(GSM):[RX]
[2021-12-29 14:09:30.202] +CMS ERROR: operation not allowed
[2021-12-29 14:09:30.202]
What can I check?
Thank you,
Stefano
