Hi There,
We connected our DF Robot serial bluetooth module to an Arduino Uno as specified in the user guide and ran a serial out loop to feed data to it across the rx and tx ports.
The comms light on the bluetooth is blinking to indicate traffic on the Rx and Tx (I think).
The problem is that we can’t discover the device when scanning from our mobile phones or bluetooth-enabled laptop.
I have surfed the support forums and most of the content assumes that a USB interface would be used to hook the module directly to a PC, so as to speak to it via the AT command set.
I was expecting to hook this unit to an Arduino, pair to it, and then to be able to read serial data from the Arduino on the paired device of my choosing.
I also expect I am missing something obvious here… any help would be appreciated.
The unit I am referring to is this one: _https://www.robotshop.com/en/dfrobot-serial-bluetooth-module.html
Cheers,
Eric.
