PDM Data over ble

[dadevelopa]

Hello guys,

I try to implement a pdm sensor on the nrf 52 dk which sends the audio data to a central device. I am using the service characteristic tutorial as a template on sdk 15.00 with softdevice 132.

Since the microphone will provide 32000 byte per second, I implemented a data length extension. It seems that as soon as I start sampling with the mic the ble connection disconnects.

Why is that and how can I solve this issue?

Thanks for your help in advance

Which pins did you assign for PDM? What is the disconnect reason?

The disconnect reason should be passed with the BLE_GAP_EVT_DISCONNECT event in p_ble_evt->evt.gap_evt.params.disconnected.reason, I expect reason to be one of the Bluetooth status codes as listed in ble_hci.h.
