Unsupported AT command

12 years 2 months ago #7786 by Easy
Quectel M20 modem datasheet shows command AT+QEXTUNSOL to turn off those nasty "+CSQN: 14, 0 , 12" messages. But :
S0*CLI> gsm send at 1 at+CGMI
                1:<<< 0 at+CGMI -- Quectel_Ltd , 11
Quectel_Ltd
Quectel_M20
Revision: MTK 0828
OK
                1:<<< 1 at+CGMI -- Quectel_M20 , 11
                1:<<< 2 at+CGMI -- Revision: MTK 0828 , 18
                1:<<< 3 at+CGMI -- OK , 2
S0*CLI> gsm send at 1 AT+QEXTUNSOL=?
                1:<<< 0 AT+QEXTUNSOL=? -- ERROR , 5

ERROR
What can I do to turn them off?

Friend, tried to enter the command with space?

voip*CLI> gsm send at 1 AT + QEXTUNSOL=?

Hi,
Yes, type more "space" between AT and QEXTUNSOL. Like f1700 saying.


AT + QEXTUNSOL = SQ, 0(1 or 2)

SQ means Signal Quality Report.
mode 0: disable, 1: enable, 2: query

S0*CLI> gsm send at 1 AT + QEXTUNSOL = SQ, 0
                1:<<< 0 AT -- OK , 2

OK

                1:<<< 0 AT -- +CSQN: 17, 0 , 12
                1:<<< 0 AT -- +CSQN: 16, 0 , 12
What's wrong? It does not turn off...

There CAN NOT be any spaces in AT command. AT +WHATEVER is just simple AT command, that gets to the modem.

Proof:
S0*CLI> gsm send at 1 AT + QEXTUNSOL
                1:<<< 0 AT -- OK , 2

OK

S0*CLI> gsm send at 1 AT + QEXTUNSOL:
                1:<<< 0 AT -- OK , 2

OK

S0*CLI> gsm send at 1 AT + WHATEVER
                1:<<< 0 AT -- OK , 2

I have resolved it finally:
gsm send at 1 AT+QEXTUNSOL=\"SQ\",0 - quotes needed.
