I realise this has been raised before but I have not found an explanation.
Similar to other comments: difficult to set it all up to work consistently, sometimes the light network forms, sometimes it doesn't, then the network drops, then the radar drops, and all in a very random fashion. (all software is up to date).
Finally did a full reset of the Edge 1030 Plus and the two light units and re-paired. Now everything seems to work.
The only snag I have is that on the light network sometimes the RTL515 shows as "Taillight" and sometimes as "Radar". When it is shown as "Taillight" it gives an "Auto Deceleration" option.
Does anybody know how to get the light network to recognise the RTL515 as a "Taillight" everytime and not just randomly?
Many thanks.
