Common problem
1. No bluetooth search
Generally caused by power supply interference, the power supply line must be added with LC filter circuit.
2. Support 3.7 power supply or not
The module is powered by 5 volts by default. You can replace the upper diode of the JDY-62 module with the 0805 package 0R resistor, or short the wire, so you can use the lithium battery.
3. bluetooth signal is too weak
Do not wire or copper under the bluetooth module antenna, or there should be no metal shielding around the antenna.
4. The current sound is too loud
Generally caused by power ground interference, it is recommended that the power amplifier wiring should not be too long, and the bluetooth ground should be separated from the power ground.
