Unmodulated TX Carrier and softdevice

[Elias Löwe]

Hi!

Is it technically possible to implement performing of unmodulated TX carrier transmission by a write to some BLE characteristic? If yes, then from what to start?

Thank you!

Thank you! Good to know.

Yes.

I don't think that you can do what you wish with the SoftDevice enabled.

You'll need to react to data received either through a custom characteristic or over the Nordic BLE UART code, then disable the softdevice to run the radio test code.

I tend to check a gpio line on power-up and switch to my DTM code before SoftDevice start-up. You could check an NVM location to do the same and then after a period erase that NVM location and trigger a reset.
