How to delete all pairings

thanks,But every time I get an error:Fatal error

[haakonsh]

There's a chance that you end up in an undefined state if you're doing connectable advertisements. 

You can broadcast as much as you like.

My approach is to call ble_gap_disconnect first, then pm_peers_delete, but fatal errors still occur. What is the correct way? thank you.

Keyboard example

[haakonsh]

What function originally returns the error?

[shenwrt]

ble_advertising_start return:ERROR 18 And  pm_device_identities_list_set return ERROR 12804

[haakonsh]

Error 0x3204 (12804dec) is defined in ble_gap.h: 

BLE_ERROR_GAP_DEVICE_IDENTITIES_IN_USE /**< Attempt to modify the device identity list while already in use by another operation. */

From the pm_device_identities_list_set API docs:

BLE_ERROR_GAP_DEVICE_IDENTITIES_IN_USE

If the device identities list is in use and cannot be set.

From  ble_advertising_init API docs: 

Return values

NRF_SUCCESS	If initialization was successful.
NRF_ERROR_INVALID_PARAM	If the advertising configuration in p_init is invalid.

Returns

If functions from other modules return errors to this function, the SoftDevice Global Error Codes are propagated.

Since the only two valid return codes are NRF_SUCCESS and NRF_ERROR_INVALID_PARAM a return code of 18dec must be a propogated return code from one of the functions inside ble_advertising_init. You will need to find the source of the error inside ble_advertising_init.
