The mesh i refer to is the HM DC app settings for bluetooth mode. There are 2 options either mesh linking (provisioning) & forwarding or standard ble. Thanks to Foden 4400, although i had tried this a while ago, resetting to factory settings I was able to connect to mesh linking and update the HM6000 to 1.8.2, the higher version wasn't available to me. I did actually manage to get sound and movement through the decoder after installing it. But then I did the install buton again by mistake and broke it no_mouth Now when i try to install SPIROM, it seems that the connection with either the HM DC app or the HM6000 disappears and the app restarts and then the HM DCC app whirls around trying to find the host device. I will keep trying, I know it works but I learnt now not to hit buttons i don;t need to :)
