1050 and smart bike lights with Varia RCT716 -> no Network Error But same configuration string with Edge 1040 no problem

Hello, is it possible that the new 1050 creates no bike light network?

I got my new 1050 today no  message bike light network created (but my edge 1040 shows this message) when I pair with RCT716 -> "no network" on connect ID button.

.The old 1040 works like a dream RCT716 turn light on when car in range and turns off after overtaking.

Thanks for your help
