Hello,

We are facing an issue with Network option set to Auto mode and a Garmin Edge 530.

When changing mode (or event switching off the light) using the button on the light itself. This does not "override" the network option to individual.

We realize that doing the same on a VARIA RTL510, it was overriding the model the network mode to individual in the Garmin Edge 530.
So we are wondering what is the trigger to switch Garmin Edge 530 Network mode.

Thank you in advance for your help,

Martin

You need to tx a sequence number in page 1 that does not match a sequence number recently received from the Edge. I recommend toggling the top bit in the sequence number relative to the last received from the Edge.

Hello,

I finally found time to test the correction, and I realize that to make it works, bytes 6 and 7 shall be set to 0x00 too.

Am I correct?

Kind regards,

Martin

This is not entirely correct.

You need
1) the sequence number to be one that was not recently sent by Edge (as described in prior post)
2) to have bytes 5, 6, or 7 have changed from what the last Edge command was

ie the edge is looking to see "did the light state change and was this not a result of a command I sent".

Sorry I didn't mention the last part as it seemed like it was implicitly true in your case.
