I'm happy to help 🙂

250kbps and +4 dBm should give you the best range, yes.

Thanks for reply.

Ok, so 250KBPS with 4DBM will give best range.

Hi Anupam

All you have to do is set the tx_output_power to 4DBM on both the PTX and PRX side.

On the PTX side this will affect the TX packet, and on the PRX side it will affect the acknowledge (ACK) packet.

In order to see a significant increase in range you have to increase output power on both sides.

There is no way to change the receiver sensitivity of the radio, other than to change the on air bitrate the protocol is running at.
In general a lower bitrate gives you better sensitivity, and 1Mbps will give you better sensitivity than 2Mbps.

Best regards
