Android Question How many bluetooth connections ?

[FFMan]

How many serial type Bluetooth connections can be supported simultaneously ?

I'd like to use 4 for relatively low speed updates say 1hz sending maybe 2 bytes of data.

if this is not possible I can integrate modules together but now there are very cheap BT modules around this almost seems easier and tidier than having wires round the garage.

I believe that the maximum number is 7. Don't remember where I saw this number.

Make sure to use a different UUID for each connection.

B4A-Bridge in Bluetooth mode creates up to 3 connections (designer, bridge and legacy debugger). It is reliable on most devices. However there are devices that don't handle the connections well.
