Hi all. I’ve flashed a generic esp32dev board to serve as a Bluetooth proxy. Now I have issues connecting it to the device (Level Touch Lock). The weird thing is that if I connect the ESP 32 to my laptop - it connects to the device and works perfectly. However if I power it from the socket - it never connects to the device. I don’t move the board - it stays in the same place both times, so I think this may be some power issues. But I’m a beginner with ESP devices so I don’t understand how I even start debugging this.
Any help would be appreciated. Thanks!
Try some other sockets. Board needs stable 5V, 500mA or more.
I’d say more than that, especially at power-on, where consumption spikes of esp32 can be in order of 1A+. Perhaps an electrolytic capacitor would help, if connected to esp32 on +5V and GND terminals, or even on +3,3V and GND terminals (it’s the matter of try and see). At least 1000uF, even better 2200uF. But long-term and stable solution is to get more powerful PSU.
Same USB Cable? Some are power only, some carry data also. Not all are reliable.
