You can call sd_ble_gap_tx_power_set() anywhere in your code after initializing the softdevice (BLE stack), to set/change the tx power. The default is 0 dBm.

Where do I have to set the tx power level? Or what do I have to do exactly? Because I found the function where I think I could or should change something in the ble_gap.h line 1373. Is this the right place to enter the output power? And how do I do this? Thank you in advance and best regards

You can enable DC/DC regulatior inside your main function, either before softdevice initialization by setting NRF_POWER->DCDCEN = 1, or after softdevice initialization by calling sd_power_dcdc_mode_set(1). To adjust the output power by calling sd_ble_gap_tx_power_set(). For data length, you will have to edit the content of your advertisement package to contain the correct number of bytes.

Thank you very much for your quick response. Regarding this I have some further questions:

Where do I enable teh DC/DC regulator exactly?
Where do I enter der parameters for my measurement?

Thanks in advance and best regards, Adrian

Hi,

Have you looked at the nRF52 Online Power Profiler? This is based on measurements done on the nRF52832, using the method described in this blog post. You can use the same Power Profiling Application if you want to do further measurements.

Best regards,

Jørgen
