Message format not received correctly

[mitchyg]

Hi,
I am using a Siemens MC35i GSM modem. Compatbility with pygsm seems quite good.

However we are using the MC35i to send messages to a remote telemetry unit. An example of a response from the remote unit is:
"INSYS GSM 4.X:
BLOCK:

100:
Ax=+01234

OK"
I believe the "OK" at the end of the query message would be confused as the end of the CMGL command response.

The actual response we get using the next_message() method is:

"Ax=+01234 4.x:BLOCK:"

Any suggestions for fixing this issue?

If you need anymore information let me know.

Thanks,
Mitch

could you send a log file containing the exchange?

Sorry it took so long to get back here. Basically the problem is with text mode SMS and timing the serial port exchange. If a SMS message ends with the characters "OK" on a new line then pygsm may not handle that correctly.

I will try and get a bit of a test log exchange on here soon.
