Thank you for your quick response.
I have checked the Baud rate at 9600 and at all other baud rate options matching them both in the sketch and on serial monitor. Changed the pin numbers in the serial pass through sketch. Checked resistors are correct value with 1k to arduino and 2k to ground. When powering up the circuit the bluetooth module lights up with rapidly flashing led. No communication, can’t get any response from AT commands. Tried BT terminal App and still no communication. I think I will send for a new Bluetooth module in case the current one is faulty. So I will not waste your time any further at the moment until I replace the bluetooth module and will let you know if I have any further success then.
Thanks a lot.
