Is there any way to set BLE txpower to -30dbm etc. using nrf52832?

Hi, I am developing a product using BLE with nrf52832.
We are aiming for a BLE communication range of around 1.0m.
However, if txpower is set to -20dbm, BLE communication will be possible farther than expected.
So, I set txpower to -40dbm because the datasheet says that it can be set to -40dbm, but this time, BLE communication was possible only at a shorter distance than expected.

Is there any way to set txpower to -30dbm between -20 and -40?

Thank you very much in advance.

Hi,

It is not possible to set the TX output power to -30 dBm in nRF52832. As you can see from the datasheet, the -30 dBm setting is deprecated (from nRF51 series) and have the same register value as the -40 dBm setting.

Best regards,
Jørgen

Dear Jørgen,

Thanks for the answer.

We will make adjustments in hardware.
