Hi team
I have a problem that bothers me for days.
I try to run demo ble_app_uart_c with
NRF_SDH_BLE_CENTRAL_LINK_COUNT=8 and NRF_SDH_BLE_PERIPHERAL_LINK_COUNT=1.
first,I use APP nRF toolbox scan and connect first board witch running this demo.It works fine.I can send data with ble_nus_string_send() and recive data from APP.
And then,after I use the second board (runs demo ble_app_uart) connect the first board,the first board use ble_nus_string_send() send data to APP will get event BLE_ERROR_GATTS_SYS_ATTR_MISSING.The other functions work fine.Two boards can send data to each other.The first board can send data to APP.
And I found that if I use nRF toolbox to disconnect the board and reconnect it .It all goes normal.But when a new peripheral connect to the central board I will get this event again.
And What I'm referring to is ble_app_multilink_central and ble_app_hrs_rscs_relay without peer manager. Please give me some advice.
There is some change that i do: main:
int main(void)
{
uint32_t err_code;
bool erase_bonds;
log_init();
timer_init();
power_init();
uart_init();
buttons_leds_init(&erase_bonds);
db_discovery_init();
ble_stack_init();
gatt_init();
nus_c_init();
if(0==isScanning)
scan_start();
/***********ADD****************/
gap_params_init();

conn_params_init();
err_code = ble_advertising_start(&m_advertising, BLE_ADV_MODE_FAST);
APP_ERROR_CHECK(err_code);
/***************************/

}else if(SendToTag==0xA1){
ret_val = ble_nus_c_string_send(&m_ble_nus_c[data_array[1]], data_array,
index);
}
if ( (ret_val != NRF_ERROR_INVALID_STATE) &&
(ret_val != NRF_ERROR_BUSY)
)
{
APP_ERROR_CHECK(ret_val);
}
} while (ret_val == NRF_ERROR_BUSY);
index = 0;
}
break;

}
}
