    I have 2 nRF2401 wireless transceivers, 1 set for transmit, and the other for receive.
    I got them from here:

    I have set the power to max (bits 8 & 9) as "11" (page 23 & 32).

    I got it to work fine, but the problem is that it is loosing packets like crazy!
    It starts to loose packets after 3-4 feet, and almost no packets go trough after like 10 feet (in line-of-sight).

    In the RobotShop website it says the range is 50 feet !!

    Am I doing something wrong??

    They work on 2.4GHz, right? This frequency range is used for a lot of other stuff, BT, Wireless LAN, microwave ovens.

    Try to test them somewhere else, in an open field somewhere outside maybe.

    transmission/receiving ranges are typically specified for open field (without obstacles like walls etc)

    Yes, it's 2.4GHz...

    Today when I got home, I tried it again, and it went about 10 feet further than yesterday... maybe tomorrow it will go 10 feet more :D

    Either way, it's still much less than expected.

    I will try to change the programming to be able to change the channels, and auto detect each other.
