BLE5182+SDK8.0-BLE_HCI_CONNECTION_TIMEOUT

[eric]

Hello,i am find an interesting phenomenon recently.I have a Nordic 5182 device(role as peripheral) and bonded to an iOS device(role as master),when i put the iOS device near a laptop which contain a BT mouse, the 5182 will receive a disconnect event with reason code 0x08( BLE_HCI_CONNECTION_TIMEOUT), 6~8 times per hour. what made me confused is that the distance between 5182 and iOS is not out of BLE range,so, i use some connection parameters like delowing:

#define MIN_CONN_INTERVAL               MSEC_TO_UNITS(20, UNIT_1_25_MS) 
#define MAX_CONN_INTERVAL               MSEC_TO_UNITS(75, UNIT_1_25_MS)
#define SLAVE_LATENCY                       0
#define CONN_SUP_TIMEOUT                MSEC_TO_UNITS(4000, UNIT_10_MS)

i have some questions: 1,Did laptop with BT enabled have some impact with another BLE device? 2,if there are some issues with my 5182 device RF circuits, how can i test and verify it? Any comments and suggestion will be appreciated. eric

Can you upload the sniffer log? Looking for retransmitts, channel map update etc. with a 4 second timeout you should be able to loose a lot of packets without loosing the link...
