Hi community,
I'm working on a BLE gamepad with custom board based on 51802 and s130, code modified from ble_app_hids_keyboard. The gamepad works like a charm on my Android phone, but I found there's a strange problem with reconnecting.
If I hold a specific button down while power up, the gamepad deletes all peers, just like the keyboard example does, but I don't know why, it still reconnect to my phone automatically, no matter whether peers were deleted. The only way to unbond to the phone is to delete bond from the phone side. I've tried several phones and several boards, all same results. Is that suppose to happen?
My pm init code is:
#define SEC_PARAM_BOND 1
#define SEC_PARAM_MITM 0
#define SEC_PARAM_LESC 0
#define SEC_PARAM_KEYPRESS 0
#define SEC_PARAM_IO_CAPABILITIES BLE_GAP_IO_CAPS_NONE
#define SEC_PARAM_OOB 0
#define SEC_PARAM_MIN_KEY_SIZE 7
#define SEC_PARAM_MAX_KEY_SIZE 16
memset(&sec_param, 0, sizeof(ble_gap_sec_params_t));
>
// Security parameters to be used for all security procedures.
sec_param.bond = SEC_PARAM_BOND;
sec_param.mitm = SEC_PARAM_MITM;
sec_param.lesc = SEC_PARAM_LESC;
sec_param.keypress = SEC_PARAM_KEYPRESS;
sec_param.io_caps = SEC_PARAM_IO_CAPABILITIES;
sec_param.oob = SEC_PARAM_OOB;
sec_param.min_key_size = SEC_PARAM_MIN_KEY_SIZE;
sec_param.max_key_size = SEC_PARAM_MAX_KEY_SIZE;
sec_param.kdist_own.enc = 1;
sec_param.kdist_own.id = 1;
sec_param.kdist_peer.enc = 1;
sec_param.kdist_peer.id = 1;
err_code = pm_sec_params_set(&sec_param);
APP_ERROR_CHECK(err_code);
the adv init code is:
void advertising_init(void)
{
uint32_t err_code;
uint8_t adv_flags;
ble_advdata_t advdata;
ble_adv_modes_config_t options;
// Build and set advertising data
memset(&advdata, 0, sizeof(advdata));
adv_flags = BLE_GAP_ADV_FLAGS_LE_ONLY_GENERAL_DISC_MODE;
advdata.name_type = BLE_ADVDATA_FULL_NAME;
advdata.include_appearance = true;
advdata.flags = adv_flags;
advdata.uuids_complete.uuid_cnt = sizeof(m_adv_uuids) / sizeof(m_adv_uuids[0]);
advdata.uuids_complete.p_uuids = m_adv_uuids;
memset(&options, 0, sizeof(options));
options.ble_adv_whitelist_enabled = false;
options.ble_adv_directed_enabled = true;
options.ble_adv_directed_slow_enabled = false;
options.ble_adv_directed_slow_interval = 0;
options.ble_adv_directed_slow_timeout = 0;
options.ble_adv_fast_enabled = true;
options.ble_adv_fast_interval = APP_ADV_FAST_INTERVAL;
options.ble_adv_fast_timeout = APP_ADV_FAST_TIMEOUT;
options.ble_adv_slow_enabled = false;
options.ble_adv_slow_interval = APP_ADV_SLOW_INTERVAL;
options.ble_adv_slow_timeout = APP_ADV_SLOW_TIMEOUT;
err_code = ble_advertising_init(&advdata,
NULL,
&options,
on_adv_evt,
ble_advertising_error_handler);
APP_ERROR_CHECK(err_code);
}
Thanks in advance.
