I use Windows 10 + Cygwin + SMS Server Tool 3 + Huawei E122 modem.

If it is only one message stored in modem memory, in smsd.log I have:

GSM1: -> AT+CPMS? GSM1: Command is sent, waiting for the answer. (5) GSM1: <- +CPMS: "SM",1,10,"SM",1,10,"SM",1,10 OK GSM1: Used memory is 1 of 10 GSM1: Trying to get stored message 1 GSM1: -> AT+CMGR=1 GSM1: Command is sent, waiting for the answer. (5) GSM1: <- OK

but no incomming message appear in the incomming folder.

The correct AT command for the first message must be:
AT+CMGR=0

Also, the last command in order to read the memory must be:

AT+CMGR=9, not =10

I think that incomming messages are numbered from 0 to 9, not from 1 to 10.

Now I also have an error in smsd.log file when the software tries to read the message no. 10:

GSM1: Trying to get stored message 10 GSM1: -> AT+CMGR=10 GSM1: Command is sent, waiting for the answer. (5) GSM1: <- +CMS ERROR: 500 (Unknown error) GSM1: No SMS received (reading interrupted)

BR,

Use a modem setting memory_start = 0.

OK. Solved... Sorry, I've missed this setting

I think this might be somehow general issue with Huawei devices when users are setting up a new system or modem. Therefore the next version 3.1.20 detects this issue, and sets start to 0 automatically, and also instructs the user to use a modem setting memory_start = 0 to avoid future error messages.

Thanks for your feedback.
