Hello.
I am developing using nrf52832 (S132 v7.0.1, SDK v17.0.0).
Since I want to bond with Android, I have created a central code that summarizes the functions that I think are necessary by referring to various sample sources.
On Android, a pairing request is displayed, but when I press connect, it becomes GATT CONN TERMINATE LOCAL HOST and I cannot bond.
Does anyone know how to deal with it?
I can't use nRF Sniffer because I don't have two boards.
Best regards.
Hello.
Does that mean I have to register NUS GATT?
It is possible to connect with Android, and I think it is a matter of bonding at that time. So I think GATT has nothing to do with it.
If I need GATT, I have to add it to nRF Connect, but I don't know the data structure. Is there any material that describes the configuration?
Best regards.
Hi
What kind of error do you see when trying to bond with your Android peripheral. Can you show me a screenshot of how you've set up the Android advertiser?
Please also note that, by default the ble_app_uart_c example project does not support bonding, so it makes sense that you won't be able to bond an Android device to it. If you try using the ble_app_hrs_c example where SEC_PARAM_BOND is set to 1, and bonding is implemented, that should work better.
Best regards,
Simon
Hello.
sorry for being late.
I compared the project where my bonding fails with ble_app_hrs_c, but I still don't understand why it fails.
Do you have any advertisements?
Best regards.
Have you included the pm_evt_handler() function and peer manager library files in your project in order to include and add bonding to your project? Just setting the SEC_PARAM_BOND to 1 won't be sufficient in a project that hasn't implemented the peer manager at all.
Best regards,
Simon
Hello.
I have included the peer manager and pm_evt_handler () in my project with the code settings below. Is there anything else I need?
#define SEC_PARAM_BOND 1 /**< Perform bonding. */
#define SEC_PARAM_MITM 0 /**< Man In The Middle protection not required. */
#define SEC_PARAM_LESC 1 /**< LE Secure Connections not enabled. */
#define SEC_PARAM_KEYPRESS 0 /**< Keypress notifications not enabled. */
#define SEC_PARAM_IO_CAPABILITIES BLE_GAP_IO_CAPS_NONE /**< No I/O capabilities. */
#define SEC_PARAM_OOB 0 /**< Out Of Band data not available. */
#define SEC_PARAM_MIN_KEY_SIZE 7 /**< Minimum encryption key size. */
#define SEC_PARAM_MAX_KEY_SIZE 16 /**< Maximum encryption key size. */
