Summary of changes

  1. For some devices sending can be slow (as an example see SIM800, it can be up to 60s) and we are returning an improper time out. Commit
  2. When SMS list is big and baudrate is not fast enough, we can suffer from timeouts while getting a sms because it is parsing the full list. Commit
  3. When parsing SMS, it can happen that we receive CRLF in the SMS payload (happened to me when receiving provider texts). So, let's say we receive
Hello <CR><LF>
World!

With the current implementation, second consume_to_stop_tag was stopping in <CR><LF> and rest of the code was failing for obvious reasons. With this patch we consume the full payload as bytes.

Thanks, can you add details also to the commit messages please? Why are we increasing the timeout, updating parsing SMS? All should be answered there.

Increase AT timeout to 10s in AT_CellularSMS::send_sms
5c49f16 
For some devices sending can be slow (as an example see SIM800, it can be up to 60s), command is being run properly but default timeout is returning an invalid error.

Increase AT timeout to 10s in AT_CellularSMS::get_sms
d676084 
When SMS list is big and baudrate is not fast enough, with default timeout we can suffer from timeout error while getting a sms because method is parsing the full list and this takes long.

@0xc0170 With all these changes of splitting commits and so on it seems that I messed up at some point. I will review code and ask for approval again.

@0xc0170 I've just fixed the build, missed variable when amending commits. I also fixed SMS test which was broken due to new list_messages implementation and new ATHandler methods. Only last commit was changed.

Could you please review again?

Fix AT_CellularSMS::list_messages breaking in text mode when CRLF is …
9e7e22d 
…contained in SMS payload text

When parsing SMS, it can happen that we receive CRLF in the SMS payload (happened to me when receiving provider texts).
As an example, we can receive:

"""
Hello <CR><LF>
World!
"""

With previous implementation, second consume_to_stop_tag was stopping in <CR><LF> and rest of the code was failing for obvious reasons.
With this commit we consume the full payload as bytes.
