since several weeks, I can't use gateway app for my CODE 25.
It seems to be ok with bluetooth, because if I lauch a video on my iphone, i have sound on the amp, and the blue light is ok.
but on the gateway app, impossible to connect. thera is not the little display (amp / iphone),
when i do a scan, then i choose the CODE V020093C8E, but I have this message:
"You may only control amps you are already connected to for audio output"
I tried to do a new configuration of bluetooth, no success,
I tried to delete app from my phone, then download again, no success.
The amp is up to date.
Problem is solved,
I see the answer in antother post.
I had changed the name of my device in the blutooth list.
I replaced CODE V020093C8E by "ampli"
It has worked as soos as I put the original name.
