How to tell if mysensors library starts up successfully?

[arraWX]

I would like to turn on a LED if a node cannot find the gateway (e.g. if the distance is too large) when the node is powered up. How can that be done?

I understand that the send command returns a Boolean that tells whether a message reached the gateway. However, if the node cannot find the gateway on power up the sketch never proceeds beyond #include <MySensors.h>. Is it possible to derive some status from this command?

you already have 3 status LED, when red led flashes there has been a transmission error.

@gohan Thank you!

The node is a sensebender micro. I would like to use the built-in LED.

I never made a node with the 3 status LEDs. It might be worthwhile for me to look more into that.

Unless you want to go the rfm69 way as they are a bit more advanced and you can read signal strength, power output and also the new driver has adaptive TX power.

@arraWX The line of code to force the node to move on if no gateway is found is

//set how long to wait for transport ready in milliseconds
#define MY_TRANSPORT_WAIT_READY_MS 3000

@Boots33 Thank you!

Those posts provide lots of useful information.

Hi,

thank you very much ! I am using the latest 2.2.rc2 version. Will give the preprocessor statement above a try ...
