common problem
1, search less than blue:
Generally caused by power interference, the power line must be coupled with the
LC filter circuit.
LC filter circuit.
2, whether to support 3.7V power supply:
The module is powered by 5V by default. You can replace the diode on the JDY-62
module with the 0805 OR resistance, or use a wire to short circuit, so that you
can use a lithium battery

3, Bluetooth signal is too weak
Do not route or cover copper under the antenna of the Bluetooth module. There
must be no metal shielding around the antenna.
must be no metal shielding around the antenna.
4, the current sound is too loud
Generally caused by the power supply interface interference, it is recommended
that the power amplifier wiring is not too long, the Bluetooth port and the
power port are separated
