I've seen a bunch of people have been using the nrf24l01+ to get ranges of 10 meters (or more) and am vaguely perplexed cause in my tests I haven't gotten anything remotely reliable over about 16 feet. This, mind you, is if I rawdog it with the pcb antennas hanging out facing each other. If I seal them up in the pretty thin plastic cases of the devices they reside in, the reception is rubbish unless I extend the pcb trace to outside the case with a little jumper wire. Even at around 10 to 15 feet, they are very directionally sensitive, so packets will start getting lost if I'm facing away from the receiver. This is all in wide open space too, a big garage with no obstructions.
I've got em set at PA_MAX, have made sure to powerUp() but didn't really find anything else in the documentation that seemed potentially helpful. Mainly I'm just wondering if people really are getting 30+ feet with two nrf2401's or if they have a more powerful reciever station or something like that. I've seen some modding the antenna: http://electronics.stackexchange.com/questions/149757/increasing-rf24-range-using-an-antenna
but it doesn't seem like everyone's doing that.
Granted, in my current setup I only actually need about a meter, so this isn't truly a big deal at the moment, but still, it would be nice to have a totally reliable 15 foot radius. So I guess I want to ask, does anyone have any cool nrf24 range maximization tips?
