Three leds light up, game over, no connection. When Ez-Gui is connected and FC is armed i was unable to replicate the problem, looks like everything is stable. Disconnecting GPS and external Mag without changing any settings is not solving this issue. It is possible that when i am not connected with EzGui issue does not occur, but I need to double check this.  \r\n\r\n--- Config ---\r\nAfroflight Naze32 acro rev5\r\nCleanflight v1.12.1\r\nExternal mag over I2C\r\nUART 1 - GPS 57600\r\nUART 2 - Serial RX - SBUS \r\nSoft UART 3 - MSP 19200 - minimOSD MW OSD 1.6 (configured for slow updates) \r\nSoft UART 4 - MSP 19200 - bluetooth \r\nRSSI over RC channel \r\n\r\n5v line checked and very stable 5,01v - 5,02v\r\n \r\n![2016-04-29 08 53 48](https://cloud.githubusercontent.com/assets/12170617/14912284/6c0586da-0dfb-11e6-91e1-78e7802ecb4f.jpg)"},"comment":{"url":"https://api.github.com/repos/cleanflight/cleanflight/issues/comments/217673917","html_url":"https://github.com/cleanflight/cleanflight/issues/2093#issuecomment-217673917","issue_url":"https://api.github.com/repos/cleanflight/cleanflight/issues/2093","id":217673917,"user":{"login":"hydra","id":57075,"avatar_url":"https://avatars.githubusercontent.com/u/57075?v=3","gravatar_id":"","url":"https://api.github.com/users/hydra","html_url":"https://github.com/hydra","followers_url":"https://api.github.com/users/hydra/followers","following_url":"https://api.github.com/users/hydra/following{/other_user}","gists_url":"https://api.github.com/users/hydra/gists{/gist_id}","starred_url":"https://api.github.com/users/hydra/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/hydra/subscriptions","organizations_url":"https://api.github.com/users/hydra/orgs","repos_url":"https://api.github.com/users/hydra/repos","events_url":"https://api.github.com/users/hydra/events{/privacy}","received_events_url":"https://api.github.com/users/hydra/received_events","type":"User","site_admin":false},"created_at":"2016-05-07T22:57:32Z","updated_at":"2016-05-07T22:57:32Z","body":"Please give more details about your GPS receiver.  Please provide a config dump.\r\n\r\nWe have quite a lot on at the moment.  Using two softserial ports was never reliable, especially for scenarios that use transmit AND receive on both ports.  Softserial implementation is OK for a low speed telemetry output (transmit only) and MSP 19200 bluetooth.\r\n\r\nAs @martinbudden suggests, using an F3 board is the way to go for the things you want to do.  You need more hardware UARTS.  Suggest SP Racing F3 EVO / MINI or similar as they also keep UART1 dedicated (shared on other boards).\r\n"}}
