EG91-EX command AT+QDAI return always ERROR

IoT Modules LTE Standard Module

Hi all,

I am trying to configure a Digital Audio interface on an EG91-EX module, but when I send the “AT + QDAI …” command the module always answers “ERROR”, but when I read the current configuration it is the same I previously try to sent.

This is the entire session:

14:30:46.328 [TX] - ATI

14:30:46.343 [RX] - ATI

Quectel
EG91
Revision: EG91EXGAR10A03M1G

OK

14:30:51.730 [TX] - AT+QDAI?

14:30:51.735 [RX] - AT+QDAI?

+QDAI: 1,1,0,1,0,0,1,1

OK

14:30:54.259 [TX] - AT+QDAI=1,1,0,4,0,0,1,1

14:30:54.262 [RX] - AT+QDAI=1,1,0,4,0,0,1,1

ERROR

Dear Sir,
If that, you may need to wait for new FW, or send email to support@quectel.com to get support from local FAE, then they can push our RD to release new FW as soon as possible. Thanks!
