Evt disconnected/advertising time out

[Umair]

I am using ble-Shield with arduino UNO on one side and Android device on other side. Most of the times i am disconnected with this error code. Can someone please tell what is the reason?

E3 :3, 86, 3, 13, Evt Disconnected/Advertising timed out

For the advertising timed out, it is normal. When you setup the advertising parameters, you likely specify advertising interval and timeout:

ble_gap_adv_params_t adv_params;

adv_params.interval    = NON_CONNECTABLE_ADV_INTERVAL;

adv_params.timeout     = APP_CFG_NON_CONN_ADV_TIMEOUT;

err_code = sd_ble_gap_adv_start(&adv_params);

In result, after the defined interval you get the advertising timeout. You can restart it again if you want.

Not sure why you get disconnected - can be a bad sw on either side or anything hw related like a bad antenna, noisy environment etc
