hi, my bluetooth module hc05 is connected to arduino via a straight rx-rx and tx-tx connection.
I have 2 modules, and to pair them with each other i used how to mechatronics' video as guidance. I configured them both and seem to be connected, but the master module's LED is blinking twice every 5 seconds.
ALSO, the master is an arduino UNO and the slave is a NodeMCU esp8366, both have straight serial connections and both seem to connect.
AT+name=HC05 1 //OK
AT+name=HC05 2 //OK
i tested the code that was in the tutorial but i couldn't get it to work.
