MiRF v2 (nRF24L01) transceiver module range

Hi,

I am evaluating two MiRF v2 (nRF24L01) transceiver modules from SparkFun but the communication is reliable only when the distance between the modules is lesser than 0.5 meters.

Does anybody have the same problem?

Any thoughts will be gratefully appreciated.

Thank you.

There are a couple of possibilities that I can think of. There may be a very large amount of 2.4 GHz traffic going on in the general area that you have your 24L01s in. One idea is to try changing the channels on the devices (as long as its the same on both) to see if your reception gets any better. Another idea is to make sure that you have the RF_PWR field in the RF_SETUP register at its highest value (11 in binary, which is the default). Bringing the data rate down to 1 Mbps can also help reception.

Thank you. I will try changing the channel.
