Activate DTM over the air interface

[saintnever]

Hi,

I'm wondering if the DTM mode can be entered over the air interface on nRF bluetooth products, as specified by Core4.2 [Vol2 Part C] 4.7.1 Activation and Deactivation of Test Mod

[endnode]

I'm afraid this Test Mode isn't BT LE DTM. At least there is nowhere DTM mentioned and all links point to BR/EDR.

Hello saintnever

As endnode stated the test mode you refer to is not for Bluetooth Low Energy. Vol 2 of the Bluetooth 4.2 specification only relates to BR/EDR (Basic Rate/Enhanced Data Rate, AKA. Bluetooth classic).

DTM (Direct test mode) for BLE is described in Volume 6, part F, and does not support OTA activation.

You can find an example for DTM in the SDK examples folder, and documentation for the example can be found here

Best regards
