Hi,
Nothing to be sorry about. Im not in any rush 
I did manage to update software, and can now choose between MessagePack and JSON.
Running now software 1.2.5.21
But my broker unfortunatley does not read either one.
I`m trying to implement this BLE reciever in Homey smart home automation hub.
On this i have one broker/client i have found that can run on the automation hub, and this only reads nodejs.
Is there any way nodejs can be added as request format in future software releases?
Best regards
Lidvar
