iPhone 8 can't connect

[letter57]

Hello,

I'm having an issue when I try to connect to my device from an iPhone 8. I'm using s132_nrf52_5.0.0_softdevice on SDK 14.2.

The phone tries to connect and then it times out. All other phones I've tried worked fine. Could it be something related to Bluetooth 5 that my device still doesn't support?

The sniffer log as below.

Hi Edvin:

               It's ok, never mind for the late reply. 

I try with Redmi Note5 and it works. The sniffer log as below.

You can have a look from packet no. 258

ps: The Redmi Note 5 Android's version is 8.1.0.

hmm. From the logs I see that both phones are disconnected in the end. 

Do you get the connected event on the nRF? And if you do, do you get the disconnected event as well? If so, what is the disconnect reason seen from the nRF Side?

The nRF is the peripheral in the connection, right?

With that phone, does it only happen on your project, or does it happen with the other projects in the SDK?

Do you use pairing? Do you handle the pairing requests on the nRF? 

BR,

Edvin
