Android Phone -> Search for available devices -> Try to pair raspberrypi-0 -> Pop up shows on phone with certain pin.
The problem is no pop up comes up on the Raspberry Pi UI. Hence the pairing request ends up with error message
incorrect or wrong pin
Weird thing is, if I send the pairing request from pi to the phone, I am able to pair the devices successfully. I have updated my Raspberry Pi's Bluetooth modules to the latest by running
sudo apt-get update followed by
sudo apt-get upgrade bluetooth bluez-utils blueman. I need to achieve this pairing because I am building an application to transfer data from Pi to phone using Bluetooth, which would need initiation of request from phone.
Bluetooth dongle: Bluetooth CSR 4.0 Dongle, specification 4.0 compliant. Supports profiles Networking, Dial-up, Fax, LAN access and headset.
