First of all>>>>>>Thank you soooo much maniacbug for the library!!!!!!
I had three problems.
1. Bad connections on the 2x4 icd connector. The module doesn't lend itself to easy hook up or plugging it into a std breadboard, not to mention the fact that they all are marked as pin 1 is pin 2 (2 is 1), because they have the pins going out the bottom of the board not the top. They all seem to be that way. So a colored ribbon cable does not match the std color code 1bro, 2rd, 3ord, 4yel, etc. Instead, it's 1rd, 2bro, 3yel, 4org, 5blu, 6grn, 7gry, 8vio.
2. Reading the documentation I thought the CE and CSN pin could be any unused I/O pin. For some reason the method "RF24 radio(9,10);" can't be changed. I had used different pins than 9 and 10,and it didn't work. I understand that the SPI interface has to match that of the ucontroller hardware, but I thought the other two pins could be any unused digital I/O.
If some one can shed some light on this it would be appreciated.
3. This applies to the module with PA+LNA: Once I fixed the other two problems, the pong (repeater) would send out one reply and then stop. The fix was to add a cap to the module. I started with a .1uf, but didn't help. Used a 220/15v cap and it worked. Did not check to see if a larger one was better or a smaller was the same.
Using the RF24 lib example "pingpair":
RANGE: (line of sight:LOS)
nRF24L01+ 30' in doors through two walls
(doors open, LOS was through 2 walls)
nRF24L01+PA+LNA approx 200' LOS
through 3 walls to outside and down the hill
