static Passkey add central ble_app_uart_c

[Autobot]

Hello everyone,

I trying to communicate nrf52832 SDK 15.0 ble_app_uart(peripheral)  to ble_app_uart_c (central) with secured purpose adding static passkey but i don't get perfect examples on central side adding passkey and peer manager.  please share some example code for adding passkey in central side for better communication.

I added peer manager concept using ble_app_gls example but my code doesn't come in this case BLE_GAP_EVT_AUTH_KEY_REQUEST. i using whitelist in peripheral side it's also need central side...???

  please refer any working code.

I have used delete bonding concept in central side, Now Its working very well Thanks for your support Simon.

Hello simon,

central some time makes this kind of error show

 0> <info> peer_manager_handler: Connection security failed: role: Central, conn_handle: 0x0, procedure: Encryption, error: 4102
 0> <warning> peer_manager_handler: Disconnecting conn_handle 0.
 0> <info> app: Disconnected.

My suspicion is that the LTK is lost on the peripheral side. Could you try to do the following:

• Erase the content of both chips
• Build and flash ble_app_uart(with bondingl)  and ble_app_uart_c (with bonding) onto your two nRF52832's
• Run both the examples and establish a bond
• Erase the content from the peripheral device and reprogram it with ble_app_uart(with bondingl)
• Try to establish a bond once again and see if the error appears

Best regards,

Simon

sorry for the long delay to replay

I erase the chip and update the same code with bonding but still i have the same problem in connection security failed below
