Getting Better Range with NRF24L01 Modules

[MasonBlake]

Hi all,

I’ve been playing around with a small MySensors network using [ NRF24L01 Modules. Everything works fine in open space, but once I put a couple of walls in between, the signal drops a lot.

I’m curious if anyone here has tried the PA/LNA versions — do they actually make a big difference in real-world use?

Also wondering about antennas:

Stick with the tiny PCB antenna, or is it really worth going external?

Any simple tweaks to cut down on packet loss when the environment is noisy?

Would love to hear what’s worked (or not worked) for you guys.

@MasonBlake yes, PA/LNA modules make a big difference. External antenna - not so much.

lower the speed, it makes a huge difference.
also, check the nRF24 power supply.

@fsgraz said in Getting Better Range with NRF24L01 Modules:

trollare l'alimentatore

Can you tell me how to lower the speed?

[fsgraz]

@sindrome73 in the gateway and the nodes you have a

#define MY_RF24_DATARATE RF24_250KBPS

The default value is RF24_1MBPS.
Just add the line above if it's not in your sketches
Both gateway and nodes must be set to the same speed.

Buon divertimento!
