Sensor causing a gateway reboot

  • I'm building a sensor for my honeybee hive. For some reason quite often when I reboot the sensor, the gateway gets stuck in a reboot loop. When I cut the power from the sensor, then the gateway boots up without issues. I have 8 other misc sensors working fine with that gateway.

    Some other information that might be useful:

    Using MysBootloader for OTA (Pro Mini 8MHz 3.3v)
    The sensor is temperature/humidity sensor. Using 5x DS18B20 and 1x DHT22

    Powering the Pro mini directly via the VCC pin from a 18650 battery. (4.2v - 3.6v)

    Sensor code

    Am I missing something or doing something no-no in the code?

  • Oh, forgot. The Gateway is simple serial gateway running on Nano.

    One thing that I notice, is that the gateway reports as being a repeaternode, which it shouldn't.

    Could you post the code that you used for your gateway as well?

  • The gateway code is unmodified Serial Gateway example. No inclusion mode and no traffic lights. As simple as it gets.

    * 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.

    * The ArduinoGateway prints data received from sensors on the serial link.
    * The gateway accepts input on seral which will be sent out on radio network.
    * The GW code is designed for Arduino Nano 328p / 16MHz
    * Wire connections (OPTIONAL):
    * - Inclusion button should be connected between digital pin 3 and GND
    * - RX/TX/ERR leds need to be connected between +5V (anode) and digital pin 6/5/4 with resistor 270-330R in a series
    * LEDs (OPTIONAL):
    * - To use the feature, uncomment any of the MY_DEFAULT_xx_LED_PINs
    * - RX (green) - blink fast on radio message recieved. In inclusion mode will blink fast only on presentation recieved
    * - TX (yellow) - blink fast on radio message transmitted. In inclusion mode will blink slowly
    * - ERR (red) - fast blink on error during transmission error or recieve crc error

  • Ok, so I replaced the 3.3V 8MHz Pro Mini with a 5V 16MHz one. Still running it from that same power source, so currently supplying 4.1V to the VCC. And no more gateway reboots.

    Both Pro Minis have the MysBootloader on them, no other component or code changes. So I guess the next thing is to wire up another 3.3V Mini, flash the bootloader on it and see how it goes.
