user63537: I want to use my Arduino with this: VAC8010F measure unit. It communicates with NRF24L01. The problem is I simply don't know which band or information it is receiving. Can somebody help me with this?
Thanks for any suggestions!

user72084: Don't have full details yet. But the VAC8010F uses modbus RS485 protocol.
My research shows that the NRF24 just transmitts and receives the MODBUS protocol to and from master/slave. I have found modbus libs and samples of code on the net. There is a command driven program to communicate with MODBUS free for linux, which is the o/s I use. I don't know about win. Anyway, once I receive the MAX485TTL interface for my ARDUINO MEGA I will write code for data  logging to p.c. then modify to use the NRF24, as I should be able to extract the ADDRESS, and CHANNELS etc, and packet construct.
Hope this is of some help.

user73963: Nordic has an app to connect to nRF
https://www.instructables.com/Send-Data-to-Mobile-Using-NRF24L01-Using-NRF-As-a-/
The app is available for all platforms.
Did not try it myself. Hope this helps.
I going to do the same, but want receive it on Android.
If you got some news, please let me know.
Thanks
