[Newbie] Need help with !TSM:ID:FAIL

[nekopep]

Hello,
I started experimenting my sensor, and I'm blocked to a specific point with some questions.

My setup:
Gateway: An NodeMcu with Nrf4 module with PA + 330uF cap on 3.3v and option RF24_PA_MIN set to avoid power issue.

Sensor: An arduino nano + Nrf4 module with PA + HC-SR04 + 330uF cap on 3.3v + regulator board for Nrf4 and option RF24_PA_MIN set to avoid power issue.

I'm using mysensors 2.2 and with RF24_PA_MIN I can now receive/send message to gateway.

Here are the logs on the sensor:

And the gateway part:

So now I'm blocked with some ID issue.
I don't know how to decode logs.
I tried https://www.mysensors.org/apidocs/group__MyTransportgrp.html
and the Log parser without success.

1/What line should I feed the Log Parser with? Do I have enabled too much log (time data on first parameter???)
2/Can someone explain better how to analyze debug output?
3/I suspect an issue with sensor ID registration,
Do I need to register my sensor to the gateway? If yes, how should I do this. I don't want to install a button yet, is it possible to pre register my slave sensor?
(or auto register option?)
4/When does the sensor enter the main loop and display distance? Once my sensor protocol is all OK?
5/Is there a more general doc on how the protocol work, I must admit I'm a bit lost trying to find the good doc :/
6/I've seen in the forum some are defining:

// Define Node ID
#define MY_NODE_ID 10
#define MY_PARENT_NODE_ID 0
#define MY_PARENT_NODE_IS_STATIC

On my sketch I got
#define CHILD_ID 1

Should I set MY_NODE_ID and MY_PARENT_ID?
Are they usefull at all, how do they compare to CHILD_ID?

Thanks for any directions :) !

You need to define the my node ID, child ID is only used to identify each sensor.

@gohan , Thks works better now.
Why someone would use CHILD_ID different than NODE_ID?
I mean if NODE_ID is needed, for what CHILD_ID is used for?

Thks!

@nekopep a sensor node can report multiple data. Example: temperature, humidity and barometric pressure. Child id is used to differentiate between the different data.

@mfalkvidd ha thanks, I've found one of your forum post where you discuss about a code you did, and I now better understand CHILD_ID.
Everything working perfectly now, thanks a lot!
