Hi,

This should work! I thought that you wanted to do have the Softdevice active all the time.

The CLI example you shared looks like a good one, though. Seems like it would be the right example to add my own custom commands.

Hi Jared,

Thanks for your quick response.

The way I wanted to implement it is like this:

Say BLE is running.

1. Issue Radio test command over BLE.

2. start 10-minute reboot timer.

3. shut down BLE stack control of radio.

4. execute radio test command

5. runs for 10 minutes

6. nordic reboots after 10 minutes

Hi,

Having directly access to the radio to test it as in the radio test example while simultaneously using BLE to receive commands is not straightforward. As the Softdevice will block the applicaiton form accessing the radio while it's in use. The exception is the usage of radio timeslots, where the Softdevice can grant the application access to the radio and it's dependent peripherals for a short timeslot. Which means that the Softdevice can interrupt the application during it's usage of the radio as it has the higher priority. So the main problem is that the radio that you want to use for retrieving commands with is the same radio that you want to test.

Have you checked the other options for CLI backends? Is none of them suitable for you?
