rces asked 7 years ago

I have gone through all the examples and got them all to work but I cannot get the Bluetooth module to work.  The RED Led is blinking which indicates it\\\’s getting power  but no sign of it showing up on a device list. The program seems to upload OK. Suggestions Bob

You obviously activated Bluetooth on your mobile phone, didn’t you? What’s your mobile phone?

So, I tried the bluetooth example and it worked from my old Android phone (S7562). The device’s name is ‘JDY-30’ (not HC-06, HC-05 or DT-04) and the pin is ‘1234’.
What’s your phone ?

Bonjour, j\’ai aussi le même problème, avec une huawey P9 lite, la connexion est plus que erratique.avec un galaxy S4, pas de problème, donc il faut croire que le soucis est plus lié au téléphone.  Same problem here with a huawey P9 lite phone, but no problem with a galaxy S4, so i think the problem is more on phone side.

Those who use the Huawei P10 are probably having problems with bluetooth, I think those who want to buy this phone in the second hand should take these problems into account. @basketball legends

@sexdolltech If your PC recognizes the JDY-30 Bluetooth device but your Huawei P10 Lite does not, try the following: ensure the device is in pairing mode, restart both your phone and the Bluetooth device, and check for any firmware updates on the JDY-30. Also, ensure Bluetooth is enabled on your phone.

Ensure that the Bluetooth module is correctly connected to your microcontroller, paying attention to the RX, TX, VCC, and GND connections. @best sex dolls
