Increasing NRF24l01 transmitting power to 18 dBm.

[Akshat]

Hello Sir,

We are using NRF24L01+PA+LNA SMA Antenna for transmission purpose using arduino using RH_NRF24.h library.

It is been set to 0dBm transitting power by default.

We need to communicate at higher range values so we need to increase its transmitting power to 18dBm.

Please guide us to accomplish the following task.

Hi,

 

The nRF24L01+ can output up to 0 dBm, and it is your external PA/LNA that needs to be controlled in order to set the given amplification.

I would recommend that you check up on how your PA/LNA needs to be controlled, and see how it is connected by checking with the module vendor. Normally the PA part is controlled via the VDD_PA pin, as this pin goes high when the radio is transmitting.

 

Kind regards,

Håkon
