conecting the radio module on a MEGA 2560 ?? !!

[samdel]

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

@samdel the mega uses different pins. follow the instructions for mega linked from https://www.mysensors.org/build/connect_radio

You have to use the correct pins for MISO,MOSI,SS,SCK and Pin 2 for the interrupt. You can get them here:
https://lynx2015.files.wordpress.com/2015/08/arduino-mega-pinout-diagram.png
You also have to modify the Arduino Mysensors in Library, inside Drivers/RFM69/RFM69.h you must specify interrupt number 4 for the mega 2560 (it's 0 for the 328).

#if defined(__AVR_ATmega168__) || defined(__AVR_ATmega328P__) || defined(__AVR_ATmega88) || defined(__AVR_ATmega8__) || defined(__AVR_ATmega88__)
  #define RF69_IRQ_PIN          2
  #define RF69_IRQ_NUM          0
#elif defined(__AVR_ATmega644P__) || defined(__AVR_ATmega1284P__)
  #define RF69_IRQ_PIN          2
  #define RF69_IRQ_NUM          2
#elif defined(__AVR_ATmega32U4__)
  #define RF69_IRQ_PIN          3
  #define RF69_IRQ_NUM          0
#elif defined(__arm__)//Use pin 10 or any pin you want
  #define RF69_IRQ_PIN          10
  #define RF69_IRQ_NUM          10
#else 
#define RF69_IRQ_PIN          2 
#define RF69_IRQ_NUM          4
#endif

PS. I've tried using the #define MY_RF69_IRQ_NUM inside the main sketch but I couldn't get it to work.

i used Mfalkvidd advices ......
its working better but stil not recognised from the gateway

@executivul The OP is using an nrf24 radio, not rfm69. Let's not give him wrong advise

[mfalkvidd]

@samdel great work. Could you post the log from the gateway?

@samdel the gateway receives the request for parens and replies, but the sensor does not "hear" the reply.

See https://forum.mysensors.org/topic/666/debug-faq-and-how-ask-for-help for information on how to troubleshoot range and power issues.

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 ;

@samdel does it start working if you move the sensor and the gateway further apart? There have been several cases where people have had trouble when the nodes are too close.

[hek]

The 3v3 line on mega was super noisy when I used it. I had to put a step down from the 5V rail.

[samdel]

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 ???

[samdel]

hi Hek

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

[hek]

@samdel said:

Empirically, I just couldn't get it working.
