I've been using the NRF24L01 with great success but I just recently found a minor issue. So far I have been using different channels to differentiate between signals but I haven't bothered to change the writing pipe. Please see below for example of how the channel and pipes are set.
So I've been just changing the channel number and I've found no problems until recently I had my project sitting on top of a speaker and I found that the channels started to interfere with each other. For example when it was meant to be listening to channel 15 it was also picking up channel 12. Then as soon as I took the speaker away it stopped happening. After repeated retesting I definitively confirmed that the speaker was causing the issue.
However I found that by changing the writing pipe as well as the channel number, this solved the issue and now my project can sit on top of the same speaker without any such issues.
My question is as follows. Can I just change a single number or letter in the writing pipe to avoid this ambiguity between channels. Like changing "0xA8E4F0F0A2BD" to "0xB8E4F0F0A2BD". Or would it be better to change it up more by replacing more characters. I ask because it will save me a lot of time if I can get away with changing just one character since it's a rather large code.
