AT commands do not have a concept of negative numbers. v.250 Section 5.3.1: may be a string of one or more characters from "0" through "9" representing a decimal integer value.

If you want to add a negative number parser to GAtChat, then please make it a separate method, so that it is very clear that a vendor 'extension' is being worked around. Regards, -Denis The team at Ofono are suggesting that Quectel (EG91) should not be returning negative numbers in AT command responses These are returned to an AT+QCOPS command where signal strength is given. Can you comment? Thanks, Alex ___ ofono mailing list -- ofono@ofono.org To unsubscribe send an email to ofono-le...@ofono.org
