Part Number: CC256XCQFN-EM
Hello Everyone
Im using the stm32 port of Bluetopia to use the board CC256xC QFN (with booster pack) to play some audio through bluetooth speaker , and it works , but some time every 3~ 4 seconds or more (random but always with a long time separation) the audio drops ,like it was stop , for a 0.5 seconds aprox. and then it continue working.
HW: NUCLEO-F446RE + Booster Pack + CC256xCQFN
FW: Bluetopia modified ( only hal/hci pin config ) from A3DP source example from STM32 porting
Testings done:
Logic analyser (salae 50Mhz Samplerate and 100Mhz) decoding the I2S , no errors detected during playback
Scope meassuring the signals integrity until debugg pins (1.8v) CLK ,FSYN and DATA_IN
Behaviors related to error:
When I Play for the first time (after a pause or very first time) it always works well , but after some seconds it get interrupted (noise)
Always the Play command seems to restar the error time , so if I play pause quickly it works
Conclution:
I think probably it happens for some asynchrony , that get accumulated and result in a stop after random time , But I don't know how solve it or get more information to validate if this is the reasson
Thanks for helps,
