I bought the keyestudio HM-10 V3 Bluetooth and it doesn't communicate with the board (Arduino uno). I tried several times multiple guides from YouTube, I can connect the phone to the Bluetooth but it responding partially to AT commands and the code doesn't responding to commands from the phone (some led on/off).
Has this happened to anyone? There is any updated video about the HM-10 of keyestudio?

Incoherent gibberish. Bluetooth does not respond to commands from the phone, only by cable from Arduino. It is in AT mode by default and changes to ( wireless) communications mode on receipt of a legitimate "non-AT" command.
