my company has a lot of q2686RD.
I’ve connected it to my pc serial port and was able to receive “ok” after sending AT.
but any other AT command only returns error.
the unit is placed on the dev kit 3.2.
boot is off and uart 1 is enabled.
the modem is from the factory. meaning its FW is the original one with no modification at all.
thanks , dor.
