Reading SMS Messages No Longer Works
-
We have just finished our design and PCB layout using the GPy. Everything was working great with v1.20.0.rc8 and modem firmware 39529. I decided to upgrade the modem firmware to 41065 and release candidate v1.20.0.rc9. Now reading SMS messages no longer works.
lte.at('AT+CMGF=1') lte.at('AT+CMGL="REC UNREAD"') # now returns ERROR response -
Removing the LTE.reconnect_uart() command that I was using previously to get the iccid() command to work seems to have fixed the problem with reading SMS messages.
Before I was getting undocumented responses from the modem: +SYSSTART and +SHUTDOWN. These responses do not appear in the Sequans manual that I can find.
