HI, I am seungwoo
I am developing data transmission using nrf52810.
A 300-kilobyte file is divided into 220 bytes and transmitted continuously.
11-27 17:24:24.416 W 15138 lbs_tag_service woo send4 packetInteration = 212total = 1543
11-27 17:24:24.418 E 2945 bt_att gatt_act_write() failed op_code=0x52 rt=143
11-27 17:24:26.236 W 15138 lbs_tag_service woo send4 packetInteration = 213total = 1543
If I send data, periodically, the above bt_att gatt_act_write () failed op_code = 0x52 rt = 143 occurs.
This error delays a lot of time.
GATT_CONNECTION_CONGESTED
added in API level 21
public static final int GATT_CONNECTION_CONGESTED
A remote device connection is congested.
Constant Value: 143 (0x0000008f)
The issue is thought to occur when the android ble stack becomes full.
I think I can not get the best speed if I get a delay of about 2 seconds every time the stack is full.
I want to know if there is a workaround.
I am using example ble_app_uart.
