I’m working with the EM9191.
Originally I was working with
Version : SWIX55C_01.07.08.00 000000 jenkins 2020/11/16 10:11:33
and I was able to register and connect to the network.
For some reason I was only able to use LTE and not 5G.
So I decided to upgrade to the latest firmware but unfortunately I am no longer able to enable the radio using “AT+CFUN=1”. It seems to return “CME ERROR: operation not supported”.
The version information is:
ati3 Manufacturer: Sierra Wireless, Incorporated Model: EM9191 Revision: SWIX55C_03.09.11.00 7bf975 jenkins 2022/06/10 20:36:01 IMEI: 355890340124093 IMEI SV: 22 FSN: 8W0462009002A1 +GCAP: +CGSM
What would be the cause of this error?
