I am successfully able to connect my phone to GPS tracker over bluetooth and send commands but was unable to to connect HC05 module to it and communicate over serial. Please help me out of this!

  • \$\begingroup\$ What is the HC05 serial port being connected to (Arduino board, PC, other)? Are you able to establish any communication with the HC05 through the serial port? \$\endgroup\$ – Nedd Nov 24 '19 at 5:29
