Hi,
I am working on nrf52840 and using below SDK and softdevice.
SDK - 16.0
Softdevice - S140
IDE - embedded segger studio.
currently using nRF52840-DK.
I am using example "ble_app_multirole_lesc_s132_pca10056" as my base code.
I am running an advertisement and scanning both simultaneously, and connecting my mobile phone with the device(mobile is as central).
my current configurations are as bellow.
/*** Scanning parameters ***/
#define NRF_BLE_SCAN_SCAN_INTERVAL (160 * 3U)
#define NRF_BLE_SCAN_SCAN_DURATION 0
#define NRF_BLE_SCAN_SCAN_WINDOW (160 * 2U)
#define NRF_BLE_SCAN_MIN_CONNECTION_INTERVAL 7.5
#define NRF_BLE_SCAN_MAX_CONNECTION_INTERVAL 30
#define NRF_BLE_SCAN_SLAVE_LATENCY 0
#define NRF_BLE_SCAN_SUPERVISION_TIMEOUT 500
/*** Advertisement configurations ***/
#define ADV_INTERVAL (160 * 10)
/*** Connection parameter ***/
#define FIRST_CONN_PARAMS_UPDATE_DELAY APP_TIMER_TICKS(30000)
#define NEXT_CONN_PARAMS_UPDATE_DELAY APP_TIMER_TICKS(30000)
define MAX_CONN_PARAMS_UPDATE_COUNT 3
I have not changed any clock accuracy related parameter.using default setting of example code.
I have the below queries.
1) once I connect with mobile phone some times devices get disconnect with error codes 0x08 and 0x28 it never stays connected for longer than 30 seconds.
-> How can I avoid this?
2) can you give some idea to choose advertisement and scanning parameters for minimum packet loss.
