I need your help. I connect this board to my arduino uno and I try to connect with serial and I get no response.
I’ve also tried searching for it using my phone to try and pair but I can never fine it.
What can I be doing wrong?
This is what I bought:
and I am using softwareserial library to connect to it on pins 2 and 3.

The board in link you posted is an empty board with no bluetooth chip
and flash memory in it. It probably won't connect.
