Hi,

[quote user="michaelcosson"]using SDK11 and S130.[/quote]

As you are using the Softdevice S130, I assume you are using one of the nRF51-series?

If you are using the nRF51-series, the -30 dBm setting should be available to use, but the -40 dBm is not.

Regards,
Joakim

I hadn't seen this post and was trying to set TX power to -30 dBm for my application. As you pointed out, -30 dBm is not available for the NRF52. However, when I unwittingly set the output power to -30 dBm, it actually sets it to 0 dBm, not -40 dBm, using SDK11 and S130.

Hi aaronxu!

If you take a look at the TX power register in the nRF52832 product specification, you can see that the -30 dBm output power is deprecated and not available on the nRF52832.

If the output power is set to -30 dBm, you will get -40 dBm instead.

Best regards,
Joakim.
