How to fix pairing on peripherals

[Hannibalhz]

Dear Nordic Engineers

I encountered a problem.I used the nrf5 sdk 17.0.2.I modify ble_app_hrs example.I found that if I turn on pairing, when I erase the flash, the pairing information in the FDS will be erased. I flashed the program again, at this time I used the phone that had been paired with the peripheral device, it would enter a strange mode, the phone would always connect with the peripheral device, but because the peripheral device had no pairing information, it refused to connect. This causes the phone and peripherals to go into a connect-disconnect-connect cycle all the time. I would like to ask how to re-establish the pairing between the peripheral device and the slave device without deleting the peripheral device pairing information on the mobile phone.

Please give me some good advice.

Best regards

Hi

I'm afraid the only way to re-establish a pairing after pairing info has been erased on one side you will have to delete pairing info on the other device as well, or else what you describe is what will happen.

Dear Simon

Thank your for your reply.My problem is  FDS of peripherals has lost the pairing data.So I imitated the loss of pairing data.I erase the flash and download program again.This course like loss of pairing data.That is why I launched this ticket.

Best regards.

Hi

I'm sorry, but I'm not sure I understand the issue here? What do you mean by "imitated" the loss of pairing? I'm afraid you can't re-establish the pairing info if it's already lost.

Best regards,
