I had my Alpine radio paired and working with my nexus 5. Then someone unpaired the device on my phone when they wanted to pair it to a different bluetooth device. Apparently the Alpine phone passphrase is '0000' (if it is needed - I can't recall it being asked for when I initially paired it and it seems that that is a "default" PIN that is attempted automatically?)
The new device did need a passphrase which was '1234'
I have been trying (unsuccessfully) to re-pair my car stereo with the phone. The message I get is that pairing was unsuccessful due to an incorrect PIN/passphrase.
I can't find anywhere in setting on how to change the passphrase - because it never asks me for one.
I am assuming somehow this is a bug and the last successful PIN is being used.
Previously my stereo would prompt if it should allow the pairing and i would select Yes - this time it doesn't work.
I have seen what looks like similar questions/issues on other forums. It seems to be a bug or at best a horrible hidden configuration somewhere.
- device A was previously paired fine.
- device A was unpaired
- new pairing to device B with a PIN
- no longer able to pair with device A - with an error message of bad PIN/passhphrase but I never supplied one for this device.
Any pointers or URLs or suggestions would be most appreciated. (aside from resetting to factory)
EDIT: To answer the questions in a comment:
- I have to look up the model number
- I cannot attempt to pair using PIN 0000 - the phone does not give me a choice to do so. I wish it would - in that case I could probably do it.
- Same as above
- I have turned off the radio - not sure how to disable BT on it - I will try that
- Yes - many, many times - as well as shutting down phone
- I am pretty sure visibility is on. It was working fine until then and I will try it with another phone later today - it is visible. The phone discovers it. Must be on
- The message is displayed on the phone.
