First I thought it could be a problem with my BLE stack, but I quite confident that this is an ubertooth-btle issue. Here is an example, of three consecutive BLE connection events. It looks like the slaves response is missing in the second event (on channel 7), but as the master is responding with its sequence number and its next expected sequence number being incremented, I think the master must have received the missing package:\r\n\r\n    systime=1439569783 freq=2474 addr=506545de delta_t=12.268 ms\r\n    01 00 41 84 2e \r\n    Data / AA 506545de (valid) /  0 bytes\r\n        Channel Index: 34\r\n        LLID: 1 / LL Data PDU / empty or L2CAP continuation\r\n        NESN: 0  SN: 0  MD: 0\r\n\r\n        Data: \r\n        CRC:   41 84 2e\r\n\r\n    systime=1439569783 freq=2474 addr=506545de delta_t=0.232 ms\r\n    05 00 92 82 2e \r\n    Data / AA 506545de (valid) /  0 bytes\r\n        Channel Index: 34\r\n        LLID: 1 / LL Data PDU / empty or L2CAP continuation\r\n        NESN: 1  SN: 0  MD: 0\r\n\r\n        Data: \r\n        CRC:   92 82 2e\r\n\r\n    systime=1439569783 freq=2418 addr=506545de delta_t=12.327 ms\r\n    0d 00 34 8f 2e \r\n    Data / AA 506545de (valid) /  0 bytes\r\n        Channel Index: 7\r\n        LLID: 1 / LL Data PDU / empty or L2CAP continuation\r\n        NESN: 1  SN: 1  MD: 0\r\n\r\n        Data: \r\n        CRC:   34 8f 2e\r\n\r\n    systime=1439569783 freq=2440 addr=506545de delta_t=12.442 ms\r\n    01 00 41 84 2e \r\n    Data / AA 506545de (valid) /  0 bytes\r\n        Channel Index: 17\r\n        LLID: 1 / LL Data PDU / empty or L2CAP continuation\r\n        NESN: 0  SN: 0  MD: 0\r\n\r\n        Data: \r\n        CRC:   41 84 2e\r\n\r\n    systime=1439569783 freq=2440 addr=506545de delta_t=0.096 ms\r\n    05 00 92 82 2e \r\n    Data / AA 506545de (valid) /  0 bytes\r\n        Channel Index: 17\r\n        LLID: 1 / LL Data PDU / empty or L2CAP continuation\r\n        NESN: 1  SN: 0  MD: 0\r\n\r\n        Data: \r\n        CRC:   92 82 2e\r\n\r\n\r\ncheers,\r\n\r\nTorsten"},"comment":{"url":"https://api.github.com/repos/greatscottgadgets/ubertooth/issues/comments/132201364","html_url":"https://github.com/greatscottgadgets/ubertooth/issues/100#issuecomment-132201364","issue_url":"https://api.github.com/repos/greatscottgadgets/ubertooth/issues/100","id":132201364,"user":{"login":"TorstenRobitzki","id":2026114,"avatar_url":"https://avatars.githubusercontent.com/u/2026114?v=3","gravatar_id":"","url":"https://api.github.com/users/TorstenRobitzki","html_url":"https://github.com/TorstenRobitzki","followers_url":"https://api.github.com/users/TorstenRobitzki/followers","following_url":"https://api.github.com/users/TorstenRobitzki/following{/other_user}","gists_url":"https://api.github.com/users/TorstenRobitzki/gists{/gist_id}","starred_url":"https://api.github.com/users/TorstenRobitzki/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/TorstenRobitzki/subscriptions","organizations_url":"https://api.github.com/users/TorstenRobitzki/orgs","repos_url":"https://api.github.com/users/TorstenRobitzki/repos","events_url":"https://api.github.com/users/TorstenRobitzki/events{/privacy}","received_events_url":"https://api.github.com/users/TorstenRobitzki/received_events","type":"User","site_admin":false},"created_at":"2015-08-18T13:14:38Z","updated_at":"2015-08-18T13:14:38Z","body":"@dominicgs Silly me, of cause you are right! ;-)"}}
