In the hcidump its saying connection timed out[not sure about the reason] When disconnection happens < ACL data: handle 68 flags 0x00 dlen 11 ATT: Read By Type req (0x08) start 0x0011, end 0x0030 type-uuid 0x2803 > HCI Event: Disconn Complete (0x05) plen 4 status 0x00 handle 68 reason 0x08 Reason: Connection Timeout Supervisory timeout in peripheral is 20.5 Seconds is it not fine ? Please let me know is there any parameter I need to configure [timeouts] for me ? After some attempts connection is successful, but I see no report map is requested by bluez. < HCI Command: LE Connection Update (0x08|0x0013) plen 14 > HCI Event: Command Status (0x0f) plen 4 LE Connection Update (0x08|0x0013) status 0x00 ncmd 0 > HCI Event: Number of Completed Packets (0x13) plen 5 handle 68 packets 1 > HCI Event: Command Status (0x0f) plen 4 Unknown (0x00|0x0000) status 0x00 ncmd 1 > HCI Event: LE Meta Event (0x3e) plen 10 LE Connection Update Complete status 0x00 handle 68 interval 12.50ms, latency 125.00ms, superv. timeout 20500.00ms Looking forward your input.
