It replies with the correct position according to the configured time interval. However, it also sends periodic messages to the server only including the IMEI every minute. Traccar replies to it but that doesn't seem to help. I believe this  issue is different to others reported before in that it works, i.e., reports the position but also sends unnecessary queries.\r\n\r\nAny help how to turn off those periodic messages is appreciated.\r\n\r\nThanks\r\nAndre\r\n```\r\n2016-05-06 21:10:40 DEBUG: [80317D16: 5001 < 176.2.22.54] HEX: 3836383638333032323037323331323b\r\n2016-05-06 21:10:40 DEBUG: [80317D16: 5001 > 176.2.22.54] HEX: 4f4e\r\n2016-05-06 21:10:41 DEBUG: [80317D16: 5001 < 176.2.22.54] HEX: 696d65693a3836383638333032323037323331322c747261636b65722c3136303530373033313034312c2c462c3139313033372e3030302c412c353130312e343634352c4e2c30313035392e353939332c452c302e30302c303b\r\n2016-05-06 21:10:41  INFO: [80317D16] id: 11, time: 2016-05-06 21:10:37, lat: 51.00000, lon: 10.00000, speed: 0.0, course: 0.0\r\n2016-05-06 21:11:40 DEBUG: [80317D16: 5001 < 176.2.22.54] HEX: 3836383638333032323037323331323b\r\n2016-05-06 21:11:40 DEBUG: [80317D16: 5001 > 176.2.22.54] HEX: 4f4e\r\n2016-05-06 21:12:40 DEBUG: [80317D16: 5001 < 176.2.22.54] HEX: 3836383638333032323037323331323b\r\n2016-05-06 21:12:40 DEBUG: [80317D16: 5001 > 176.2.22.54] HEX: 4f4e\r\n2016-05-06 21:13:40 DEBUG: [80317D16: 5001 < 176.2.22.54] HEX: 3836383638333032323037323331323b\r\n2016-05-06 21:13:40 DEBUG: [80317D16: 5001 > 176.2.22.54] HEX: 4f4e\r\n2016-05-06 21:14:40 DEBUG: [80317D16: 5001 < 176.2.22.54] HEX: 3836383638333032323037323331323b\r\n2016-05-06 21:14:40 DEBUG: [80317D16: 5001 > 176.2.22.54] HEX: 4f4e\r\n2016-05-06 21:15:40 DEBUG: [80317D16: 5001 < 176.2.22.54] HEX: 3836383638333032323037323331323b\r\n2016-05-06 21:15:40 DEBUG: [80317D16: 5001 > 176.2.22.54] HEX: 4f4e\r\n2016-05-06 21:20:27  INFO: [5302B49F] connected\r\n2016-05-06 21:20:27 DEBUG: [5302B49F: 5001 < 176.4.31.19] HEX: 23232c696d65693a3836383638333032323037323331322c413b\r\n2016-05-06 21:20:27 DEBUG: [5302B49F: 5001 > 176.4.31.19] HEX: 4c4f4144\r\n2016-05-06 21:21:36  INFO: [0ED82D75] connected\r\n2016-05-06 21:21:36 DEBUG: [0ED82D75: 5001 < 176.2.102.73] HEX: 23232c696d65693a3836383638333032323037323331322c413b\r\n2016-05-06 21:21:36 DEBUG: [0ED82D75: 5001 > 176.2.102.73] HEX: 4c4f4144\r\n```"},"comment":{"url":"https://api.github.com/repos/tananaev/traccar/issues/comments/217578339","html_url":"https://github.com/tananaev/traccar/issues/1928#issuecomment-217578339","issue_url":"https://api.github.com/repos/tananaev/traccar/issues/1928","id":217578339,"user":{"login":"tananaev","id":1161863,"avatar_url":"https://avatars.githubusercontent.com/u/1161863?v=3","gravatar_id":"","url":"https://api.github.com/users/tananaev","html_url":"https://github.com/tananaev","followers_url":"https://api.github.com/users/tananaev/followers","following_url":"https://api.github.com/users/tananaev/following{/other_user}","gists_url":"https://api.github.com/users/tananaev/gists{/gist_id}","starred_url":"https://api.github.com/users/tananaev/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/tananaev/subscriptions","organizations_url":"https://api.github.com/users/tananaev/orgs","repos_url":"https://api.github.com/users/tananaev/repos","events_url":"https://api.github.com/users/tananaev/events{/privacy}","received_events_url":"https://api.github.com/users/tananaev/received_events","type":"User","site_admin":false},"created_at":"2016-05-06T22:24:45Z","updated_at":"2016-05-06T22:24:45Z","body":"I'm not sure if it's possible to turn them off.
