hi Hek

how do you measur the noisyness?? with a fluck in AC ?? what are the limits .?

2 metres away stillthe same result

i also tried to load an other sketch asthe one i was using was tuned by me....
still the same

i finaly tried using an other arduinoboard (original one) and it is working good......

the one who was not working correctly was this one ;
https://www.amazon.fr/gp/product/B00OPO44UE/ref=ox_sc_act_title_32?ie=UTF8&psc=1&smid=A21548PJTFXT87

di i have to put it to trash or is there a way to test it or to make it working ???

i double (triple) checked connections all ok
i checkes power suplies ; all ok
i have condansators installed on each nrf24
and i am testing it on my desk so no long distance to travel...
......

i tried to assigne a node id ;

i have a problem to make a radio NRF24L01 working on a MEGA 2560 to create a sensor node

i am using the standard mysensor connection (its working for me on a nano)
but when i use the same connection on the mega it is not working at all
i select the good board type before uploading .....

serial is giving me this message :

Starting repeater (RNNRA-, 2.0.0)
TSM:INIT
!TSM:RADIO:FAIL
!TSM:FAILURE
TSM:PDT

the radio moduleis working correctly on an other node.....

is there anithing i dont know to use a MEGA....
is the connection the same than on a nano

PS sorry for my bad english

this kind of optic fiber is probably only plastic so for a full DIY , you can use also fishing wire with a big power led or an old chistmass tree optic fiber lighted.....
