Question

How to control using DTM commands (not HCI / ACI)

I want to use the 2-wire Direct Test Mode defined in Bluetooth Core Spec Vol. 6 Part F for RF testing of my STM32WBA custom board.

I've already tried BLE_TransparentMode. While HCI / ACI commands work, DTM commands don't respond.

Is it impossible to control with 2-wire DTM commands in BLE_TransparentMode?

Please let me know if there's any way to do this.
