Just a followup question, since I don't know much about bluetooth in general. Do all the generations of AirPods use Bluetooth Classic? I mean, if I use STM32WB/WBA, will I lose compatibility with all the generations of AirPods, or just the first one?...

I've cracked it! This value: "DMA_CTR1_DDW_LOG2_0" should be changed to this: "DMA_CTR1_DDW_LOG2_1"Apparently DAC only accepts the world-aligned access.And also one more mistake here: "1 << DMA_CBR1_BNDT_Pos" should be: "2 << DMA_CBR1_BNDT_Pos" becau...
