Re: BM20 VDDA switches off
Open case since Nov 25, 2018.
Not yet got any feedback, case status still "new".
I have developed the module by implement the Bluetooth BM20.
When the module standby for some period of time such ~30 minutes or few hours, when play music or call in there is no audio output.
But since I connect with tool, when query the status it report correctly such as on stream, just no audio.
Disconnect rand reconnect does not solved, only power off and power.
1. When happen, and power off there is no "power off" tone as well.
2. It must be reset
3. Sometime power off then on to fast, the symptom stills remain
4. Test on BM20_EVB, also experienced same symptom
5. All test with battery connected no USB connected until need to query
Please advise - what to check.
Also, what is the maximum current supply from SYS_PWR?
