Ok so I managed to put both into AT mode and I have configured both modules.
The master unit HC-05 when in slave mode I am able to connect my phone and read serial but when in Master mode its not discoverable.
I tried various methods to connect to the HC-06 Slave unit from the HC-05 using the LINK command but although AT command says OK it is not transmitting data to the HC-06
I can however manually connect to the Slave HC-06 again with my phone and send data to it.
Also apparently the Master unit is supposed to automatically connect to a slave unit but mine don’t
What confuses me the most in this config link setup is how can it (pair) or link without a password?
Does anyone have an example pairing config settings for both HC-05 and HC-06 to get the HC-05 sending data to the HC-06 please?
All I changed on the SLAVE unit was the SPEED, NAME and PASSWORD
On the MASTER unit I did SPEED to match above, NAME and PASSWORD
I tried the following link setup
