Hi,
I am trying to send a SMS via the Quectel tool QCOM, but I fail.
My steps:
at+cmgf=1
OK
at+cscs?
+CSCS: “GSM”
OK
at+cmgs=“my mobile number”
I know you should write text SMS text and end with Ctrl+Z, but how do you do that in QCOM?
According to this example with Qnavigator, you simply type ctrl+z on your keyboard. I suppose Qcom should be working in the same manner.
The result is the same with QNavigator, ie the communication hang at sending a SMS.
Please note I have not any main antenna connected.
This is a must?
If so, this might explain the hanging situation.
Which AT command to use, to check if the module is connected to a radio base?
