External LED not working

I have problem with my external led indicator. I bought two led modules like this: http://www.goodluckbuy.com/apm-px4-pixhawk-flight-controller-universal-rgbled-bln-module-dual-led.html and both not working. After connecting led module to pixhawk internal led switch off but external don’t flash. Could someone managed to work this module with pixhawk?

These devices connect to the i2c port of the Pixhawk and have a set address that the software knows. If there are two units connected with the same address they will fight. There can only be one unit connect like this. The internal LED is connected differently then the external one so they should not interfere with each other.


Unfortunetly problem exist even with led only connected so it’s not an duplicated address probem :confused:
