STM32WB55: DTM/aci_hal_tone_start not activating

[BPeet.1]

Hi,

I try to start a a continuous waveform (CW) from the STM32WB radio using theaci_hal_tone_start command from the DTM suite. I execute the following commands:

hci_reset( );

HAL_Delay( 10 );

aci_hal_set_tx_power_level( 1, tx_pow );

aci_hal_tone_start( RF_Channel, offset);

which all return success.

At that point the ble advertisements stop so it is doing something, but I do not seem to be getting the CW.

Am I missing some call to eg 'activate; DTM ?

Or something else I might be doing wrong ?

(I looked at the PER testbench code, but did not see anything special in the start_TX function of that codebase, there the same steps are done except of course the different last call to start transmitting packets)

Thanks

Bram
