Hello,
Recently started tinkering with nRF24 modules. I have a few doubts to clear.

  1. The pipe address is 5 bytes long. Why these above addresses are 6 bytes?
  2. Can I use any 5 byte address for these pipes?
  3. According to this wiki page, Welcome to ELECFREAKS WIKI — ELECFREAKS WIKI
    nRF module has "126 RF channels" & one RF channel can have upto 6 pipes. So how many nRF modules can talk to a single such module? is it 126 x 6 numbers?

    I am trying to implement a wireless sensor network with hopping feature included. Till now my progress is sending data from one node to another in simplex mode. Now, trying to figure out how to receive data from more than one TX node (simplex mode)
    Data loss in RX node (Wireless sensor monitoring using nRF24L01+) - #8 by nightcrawler218 - Project Guidance - Arduino Forum
    I was using a different library (included in the above thread) but planning to learn & utilize the RF24 library.
    Any help shall be appreciated.
    Thank you.
