NRF51822 re-authenticating

[biao]

HI In the case the keyboard miss the LTK（or bonding info）, how can I start a reconnect or re-authenticating to let the host and device to generat a new one?

When I replies without the keys like the below pictures ，the central reply me nothing .

And the function sd_ble_gap_authenticate can't run well in any case（eg after sd_ble_gap_sec_info_reply(m_conn_handle, NULL, NULL) , in the function on_encrypt_timeout ）

it just return NRF_ERROR_INVALID_STATE 。

   I want to get a way to start a re-connect or re-authenticating as both the central and slave has no bonded info do. the s110_nrf51822_7.0.0_releasenotes.pdf  and the

comment statement of ble_bondmngr.c tell me that there is some way to do that.

development environment :

SDK 6.0.0

SoftDevice7.0.0

app:bluetooth ble keyboard

host:iphone4s ios7.1,2

Hi biao,

This depends on how the peer handle it. In this case you would most likely have to delete the bonding from the iPhone for it to issue a new Pairing Request and do a re-authentication.
