#84164

I think these two issues have similarities, and it needs to be explained that nrf52840 works properly.These two issues are holding my product back, I can help in any way I am able..

In addition, Android iOS is normal.

The difference is that Android has been upgraded to L4 security level, while iOS remains at L1.

Android requests the pairing code and raises the security level, iOS does not request the pairing code.

Looking at it this way, iOS is also not working properly, it's just not failing to connect.

@zhang-wenchao, please, fetch latest main and check again. It should be working already. PR #80712 automatically fixed the issue after having BT_CTLR. That enabled proper ECDH handling. Same for #84164.

I'm still having issues with my iOS device. to keep it consistent with you, I also changed to esp32c3-devkitm

Sorry, I don't know how to log on iOS.

This example bluez works fine, Linux connection is successful and the security level is increased. there are still problems with ios. although it can connect, the security level is not improved.

Now the problem mainly lies in iOS. both examples Android and Linux are no problem.

I see you don't have an iOS device, I can help you test it if possible.

@zhang-wenchao @sylvioalves FYI, there are some changes coming to the ECC Kconfig options, however that shouldn't necessitate any changes, unless you've been explicitly setting the BT_SEND_HCI_ECC_EMULATION option (which will soon not exist anymore): #84268

Just to rule out that this isn't the cause, could you try with #84282?

[00:00:57.472,000] bt_smp: Unexpected SMP code 0x08

FWIW, this is:

#define BT_SMP_CMD_IDENT_INFO			0x08
