The RX timeout will occured over 200 meters and gateway can not receive the data from node. At the longest distance, the RX package RSSI is about -80. I tried to change a lot of parameters, but it didn't work. After joined, node will automaticlly reduce the TX power , datarate = DR12, region eu433,  I have no idea about it and I can't find out where is the problem.\r\nlooking forward to your answers, thanks!"},"comment":{"url":"https://api.github.com/repos/a5086397/cwang/issues/comments/381828276","html_url":"https://github.com/a5086397/cwang/issues/1#issuecomment-381828276","issue_url":"https://api.github.com/repos/a5086397/cwang/issues/1","id":381828276,"user":{"login":"a5086397","id":32294316,"avatar_url":"https://avatars1.githubusercontent.com/u/32294316?v=4","gravatar_id":"","url":"https://api.github.com/users/a5086397","html_url":"https://github.com/a5086397","followers_url":"https://api.github.com/users/a5086397/followers","following_url":"https://api.github.com/users/a5086397/following{/other_user}","gists_url":"https://api.github.com/users/a5086397/gists{/gist_id}","starred_url":"https://api.github.com/users/a5086397/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/a5086397/subscriptions","organizations_url":"https://api.github.com/users/a5086397/orgs","repos_url":"https://api.github.com/users/a5086397/repos","events_url":"https://api.github.com/users/a5086397/events{/privacy}","received_events_url":"https://api.github.com/users/a5086397/received_events","type":"User","site_admin":false},"created_at":"2018-04-17T03:48:31Z","updated_at":"2018-04-17T03:48:31Z","author_association":"OWNER","body":"I've been looking at code, find where  I can improve the value of  RSSI and increase  the communication distance"}}
