Revision:

Parent:
5:b935404dcf7c 
C027 compatibility: don't check the response filename when doing a block read as teh Sara-G350 module doesn't always return it. Increase the minimum wait time for a read response and the maximum wait time as well, again 'cos Sara-G350 is not as responsive as Sara-U201.
