Environment

Controller: MyController.org version 0.0.3.Alpha2
Gateway: MQTT
Mysensors version: 2.0.x
Number Nodes: 2
Radio Type: MY_RADIO_NRF24
Node CPU: Arduino Nano ATmega328

Issue

When I tried to add another node (any sensor type or no sensor at all) I am getting error, looks like the new node is not able to contact the gateway via radio. I enabled full debug and I am seeing the following messages:

I replaced the CPU, the radio, I added 4.7uf capacitor, 2 other nodes communicated properly.

I need some help to understand the messages.

Thank you very much,

Overview

This is my project to add TFT LCD 1.8" color display to my home automation.
I use TFT LCD 1.8" Full Color 128x120 SPI Display module compatible with Adafruit ST7735 Driver.
Since Mysensors Radio also uses SPI, I connect the display using "any pin" method, it is slower than SPI but it will not interfere with the radio.

WiringThings Up

Start by connecting the radio module.

Required libraries

Adafruit ST7735 Library
Adafruit GFX Library If you want to display bitmap images.

Example

This example will:

• Request the current date and time from the controler when power on/reset.
• Use "display mask" to only update parts of display to improve performance.
• Update display every minute.
• It uses Arduino Time library to manipulate date and time.
• It display message sent by your controller.

/***************************************************
 * The MySensors Arduino library handles the wireless radio link and protocol
 * between your home built sensors/actuators and HA controller of choice.
 * The sensors forms a self healing radio network with optional repeaters. Each
 * repeater and gateway builds a routing tables in EEPROM which keeps track of the
 * network topology allowing messages to be routed to nodes.
