Influence of interference on Bluetooth HC-05
13vadimka13 asked 2 years ago
I share my experience. If you use a cheap Chinese converter to get 5 volts from 3.7 and you have problems with a fixed solution that is constantly floating, then shield the converter board and the bluetooth module with foil with tape. I also brought the antenna (9 cm) to the opposite part of the housing, and placed the module itself there. Now the converter choke interference does not affect the HC-05 radio signal. The Ardusimple board + HC-05 consumes 150 mA
