What do the Error led flashes mean?

[gohan]

I haven't used much the status leds but I never seen that

[sundberg84]

@Woodside I can see the error flash when a node is requesting time or count from the controller and the answer back doesn't reach and/or get ack from the node. Not sure the general use for the led and curious as well but this is one thing I noticed.

If you are a code guy (I'm not) I'm pretty sure it's easy to find out by looking at the source code.

[Woodside]

Has nobody implemented the error LED and wondered what the flashes mean?:worried:

[gohan]

What do you see in the serial log when you see the red led flashing?

[Yveaux]

@Woodside In fact, I have implemented the current Indication-code, which controls the error led behavior ;-)
The number of red flashes indicate the type of error occurred.
For 2.1.1 (it's defined in https://github.com/mysensors/MySensors/blob/2.1.1/core/MyIndication.h, in principle it can change with MySensors releases) the list is as follows:

INDICATION_ERR_HW_INIT             HW initialization error
INDICATION_ERR_TX                  Failed to transmit message.
INDICATION_ERR_TRANSPORT_FAILURE   Transport failure.
INDICATION_ERR_INIT_TRANSPORT      MySensors transport hardware (radio) init failure.
INDICATION_ERR_FIND_PARENT         Failed to find parent node.
INDICATION_ERR_GET_NODEID          Failed to receive node ID.
INDICATION_ERR_CHECK_UPLINK        Failed to check uplink
INDICATION_ERR_SIGN                Error signing.
INDICATION_ERR_LENGTH              Invalid message length.
INDICATION_ERR_VERSION             Protocol version mismatch.
INDICATION_ERR_NET_FULL            Network full. All node IDs are taken.
INDICATION_ERR_INIT_GWTRANSPORT    Gateway transport hardware init failure.
INDICATION_ERR_LOCKED              Node is locked.
INDICATION_ERR_FW_FLASH_INIT       Firmware update flash initialisation failure.
INDICATION_ERR_FW_TIMEOUT          Firmware update timeout.
INDICATION_ERR_FW_CHECKSUM         Firmware update checksum mismatch.

The first error gives 1 flash, the 2nd 2 flashes etc. Count the flashes and this table tells you exactly what is wrong.

I admit it sometimes is hard to count the flashes, especially when multiple errors are reported sequentially, but the basis is there.
Always open to suggestions!

[Woodside]

@Yveaux That is useful information, thank you.

Rather than trying to count the flashes to work out what is going on, can I output the error message(s) to the serial monitor?

@gohan Attached is the serial log from startup and some successful commands from Vera to turn the relays on and off. I cannot see any errors? When the Gateway starts up there are about 29 flashes of the error led (difficult to count exactly).

For a successful relay on or off there are two error flashes. According to the MyIndication.h extract from @Yveaux, corresponds to 'Failed to transmit message'. But the relay switches correctly and there are no transmit errors in the serial log.:confused:

[gohan]

Did you try with a gateway with version 2.2.0?

[Yveaux]

@Woodside You can define MY_INDICATION_HANDLER and implement your own indication handler which translates the callbacks to serial output (or to a different LED indication pattern), e.g.:

#define MY_INDICATION_HANDLER 
// ....
void indication(indication_t ind)
{
  switch(ind)
  {
    case INDICATION_TX:          Serial.println(F("TX")); break;
    case INDICATION_RX:          Serial.println(F("RX")); break;
    // ....etc...
    case INDICATION_ERR_HW_INIT: Serial.println(F("ERR_HW_INIT")); break;
    case INDICATION_ERR_TX:      Serial.println(F("ERR_TX")); break;
    // ....etc...
  }
}

[gohan]

@Yveaux this could be an idea to have a lcd on the gateway that reports the error description and node affected.

[Yveaux]

@gohan Have a look at this gateway from @Japio : https://www.openhardware.io/view/349/MySensors-ESP8266-MQTT-gateway
He used the indications to get more feedback using LEDs.

[Woodside]

Thanks both.

I will try the gateway with version 2.2.0 first.
