@larox11 found this when trying to send AT+CSIM commands longer than 500 bytes to the modem. As the buffer behind this method is only 127 bytes long and the strcmp was evaluated erroneous, this stopped users sending longer commands in several chunks.

There was a problem hiding this comment.
This change is wrong, since the +++ sequence must not be followed by NL. After +++ no other bytes must follow for a certain time. As far as I recall, for one second. The only appropriate change would be to allow for longer messages. But that is a larger change, affecting the buffer handling.

Thanks, @robert-hh. I will retract this change and close the PR. |
