Node doesn't recieve message from gateway

[keczejo]

@TheoL about 50cm but i tried putting node few meters away

[electrik]

@keczejo said in Node doesn't recieve message from gateway:

?TSF:MSG:SEND,10-10-255-255,s=255,c=3,t=7,pt=0,l=0,sg=0,ft=0,st=OK:

This looks like the destination is 255. Can you post your node code?

[keczejo]

@electrik it's led dimmer code with node id 10 added

[TheoL]

@keczejo Could you please post the code and if it's not too hard the schematics. It makes it easier to help you find the problem.
I have 2 fairy lights led dimmer approximately 2 - 3 meters from the node. But so far no problem with them. I upgraded to the latest recently and discovered that adding this config line solved my problems. Apparently I didn't have the good quality NRF radio's but this line solved it for me:

#define MY_RADIO_RF24
#define MY_RF24_DATARATE RF24_1MBPS // see (https://forum.mysensors.org/topic/4631/nrf24l01-can-t-find-parent-on-gateway/7)

Needs to be on all nodes and Gateway

[keczejo]

I added :

#define MY_RF24_DATARATE RF24_1MBPS // see (https://forum.mysensors.org/topic/4631/nrf24l01-can-t-find-parent-on-gateway/7)

but it didn't help.

 * REVISION HISTORY
 * Version 1.0 - February 15, 2014 - Bruce Lacey
 * Version 1.1 - August 13, 2014 - Converted to 1.4 (hek)
 *
 * DESCRIPTION
 * This sketch provides a Dimmable LED Light using PWM and based Henrik Ekblad
 * <henrik.ekblad@gmail.com> Vera Arduino Sensor project.
 * Developed by Bruce Lacey, inspired by Hek's MySensor's example sketches.
 *
 * The circuit uses a MOSFET for Pulse-Wave-Modulation to dim the attached LED or LED strip.
 * The MOSFET Gate pin is connected to Arduino pin 3 (LED_PIN), the MOSFET Drain pin is connected
 * to the LED negative terminal and the MOSFET Source pin is connected to ground.
 *
 * This sketch is extensible to support more than one MOSFET/PWM dimmer per circuit.

@keczejo Not sure what the W5100 takes for power. I'd try to power the NRF on the gateway with a power regulator.

Also if you disconnect the W5100 and set the getway up as a serial gateway, will it be able to find the parent? I'd try that as a first step

[keczejo]

@TheoL
W5100 is powered from 5V because it has own regulator. I changed to serial gateway and it's node still doesn't find parent.

[TheoL]

@keczejo Finding the root cause is hard. Because you currently have no working device. If you have some spare try changing radios. Move the node further away from the gateway. And things like that.

[electrik]

What module are you using? There are many flaky ones around.

[keczejo]

I changed node arduino to mega and it worked first try. Thanks for help
