My module information:
AT+CMGR
EG915UECABR03A02M08
I want to record uplink sound, as reported in the manual, with the command AT+QAUDRD=1,“UFS:A.wav”,13,0 but I get the answer +CME ERROR: 902. Where is the issue?
Best regards.
Dear @johndoe ,
Good Day,
Thank You reaching out to us.
From your mentioned issue, the +CME ERROR: 902 indicated invalid parameters.But i have checked your command have no issues.cCan you try again maybe there is a mistake using “UFS:A.wav” quotation mark.
Can we get these additional info:
a) Get the full firmeare version(AT+QGMR)
b) Is the issue observed intermitten?
c) Are you using our EVB kit or or own pcba for test?
Thank you!
Hi!
Thank you in advance for your quick answer.
I also tried with “A.wav” and i verified that quotation marks are the double straight forward quotes and should be the right ones. Additional info requested are:
a) full firmware version is EG915UECABR03A02M08_01.200.01.200;
b) I have always observed the answer +CME ERROR: 902;
c) I have my own pcb and audio channel used is microphone designed according to the guidelines reported in the hardware design document.
Best wishes.
I solved.
My issue was generated when I gave the command in C format because for double quotes in the string I didn’t use the escape character e.g “AT+QAUDRD=1, "A.wav",13,0”.
Many thanks for your attention.
