QUESTION
I am desperatly trying to upload some audio file to the internal memory of a SIM800C, so far this is what I've been able to do, but the uploaded file seems void, and doesnt play any sound. But with AT+FSLS=C:\\
I can see the file is there.
Here are the AT commands I am using:
...ANSWER
Answered 2019-Jul-07 at 08:29I think the post you mentioned is right. In App note, page 13, there is also an example.
So in your program, suppose you have a local file ~/tts0.amr with size 5030 bytes, (tts2.amr is the file name inside modem)
- read file ~/tts0.amr to memeory variable, like amr_data for exam;
- send "AT+FSWRITE=tts2.amr,0,5030,10" to modem, waiting for ">" instead of "OK";
- write amr_data to modem, just like the step above;
- if the size matching, modem shall return "OK" now.
