@lewisxhe I've just tried that "PlayMP3FromSPIFFS" example sketch too and I cannot hear any audio from the watch. Days ago I used the "ESP32 Flash download tool v3.9.3" and flashed the watch with the V3 bin file "twatch-2020-v3-220531.bin" found here. Do we have to flash the T-Watch also with the "2020-V3_Speaker.bin" bin file? If so, what address should I put on the "@" column of the flash tool? I cannot find the value anywhere
