No it wasn't a lie. It was caused because I didn't close the bluetooth connection before I disabled softdevices.

So it seems that the error message - "Not Enabled" - was a lie, then ?

Anyhow, if your issue is resolved, verify the answer:

I didn't know I had to close active connections and stop advertising before I can call sd_softdevice_diable(). I added the changes and it is working.

Hi,

[quote user="jsdey4"]when I call sd_softdevice_disable(). I get error NRF_ERROR_SOFTDEVICE_NOT_ENABLED.[/quote]

Are you sure the SoftDevice is enabled when you get this? Please double check.

[quote user="jsdey4"]Do I need to disable anything else before calling sd_softdevice_disable()?[/quote]

You should stop any active connections, advertisers or scanners before calling sd_softdevice_disable()

I'm going to receive commands over BLE and then I will enter the radio tests by disabling softdevices.

I'm trying to implement it but I'm having an issue occur when I call sd_softdevice_disable(). I get error NRF_ERROR_SOFTDEVICE_NOT_ENABLED. Below is the call stack at the point of this error. Do I need to disable anything else before calling sd_softdevice_disable()?

Hi,

This is not straightforward, and I am tempted to say it is not possible. The radio test example does not use a SoftDevice at all but controls the radio directly, based on UART commands. If you want to use BLE with any software we provide that would have to be via the SoftDevice, and the SoftDevice has full control over the radio.

You could perhaps use the SoftDevice to receive commands over BLE, and then disable the SoftDevice to do as previously instructed, before re-enabling the SoftDevice again. Alternatively, you could use the radio timeslot API. In any case, this would mean that you could only get the test state in a short period, before moving to BLE again to receive new command(s).
