Problems using 6 RF24 transmit nodes, 1 receiver with arduino nano and sensors

Hello Forum,

Until a few days ago I was very happy with a network of 1 receiver and 5 transmitters sending temperature, humidity, lux and outside temperature.

I really appreciated the RF24 and RF24Network librairies and examples by James Coliz !
I used version "Copyright (C) 2011 James Coliz, Jr. maniacbug@ymail.com'".

Set up is :

  • Receiver Nano + RF24 with power regulator works with or without extra antenna.
  • Transmitters ( 5x ) Nano + RF24 with power regulator works with or without extra antenna.
  • Transmitters with BH1750/BME280/DS1820 sensors.

So I wanted to add another transmitter number 6 but this generates strange problems.

I exchanged all components Nano boards cabling to exclude hardware problems.

In the attachment the code I am using and the screenshot showing the data from the transmitter.

This code works perfectly if I use nodes until the number of 5, when I use 6 or higher the problems arise.

As you can see from the screenshot it transmits successful 5 times then failes and will not recover.
Also the receiver does not detect node 6 even the first 5 successful times.

As mentioned I can exclude hardware problems so it comes down to the code I used or there is a library issue, from what I read the NF sensors can receive data from up to 6 sensors.
I dont want yet to use the mesh set up and 6 sensors are enough for now.

Can you help me with this problem ?
If not please indicate whom I could ask !

Kind regards,

Peter Liebeton
