It works fine on hardware UART 6 (TX6), but doesn't on soft serial TX (neither mapped to pin C07 - RX6, nor A01 - LED_STRIP).\r\n\r\nInterestingly FPORT works fine on soft serial, so soft serial isn't generally broken. I'm trying to avoid it though because of the cpu overhead.\r\n\r\nThere are reports out there that say it should work on that board, but those were on 3.2, not 3.3 nightly that I'm trying.\r\n\r\n```\r\n# diff\r\n\r\n# version\r\n# Betaflight / LUXF4OSD (LUX4) 3.3.0 Feb  1 2018 / 14:22:12 (8738e7d62) MSP API: 1.37\r\n\r\n# name\r\n\r\n# resources\r\nresource MOTOR 1 A03\r\nresource MOTOR 2 B00\r\nresource MOTOR 3 A02\r\nresource MOTOR 4 B01\r\nresource MOTOR 5 NONE\r\nresource PWM 4 NONE\r\nresource SONAR_TRIGGER 1 NONE\r\nresource LED_STRIP 1 NONE\r\nresource SERIAL_TX 11 C07\r\nresource SERIAL_RX 6 NONE\r\nresource LED 1 NONE\r\n\r\n# mixer\r\n\r\n# servo\r\n\r\n# servo mix\r\n\r\n# feature\r\nfeature SOFTSERIAL\r\nfeature TELEMETRY\r\nfeature AIRMODE\r\nfeature ANTI_GRAVITY\r\nfeature DYNAMIC_FILTER\r\n\r\n# beeper\r\n\r\n# map\r\nmap TAER1234\r\n\r\n# serial\r\nserial 5 64 115200 57600 0 115200\r\nserial 30 2048 115200 57600 0 115200\r\n\r\n# led\r\n\r\n# color\r\n\r\n# mode_color\r\n\r\n# aux\r\naux 0 0 3 1700 2100 0\r\naux 1 13 2 1700 2100 0\r\naux 2 35 1 1700 2100 0\r\n\r\n# adjrange\r\n\r\n# rxrange\r\n\r\n# vtx\r\n\r\n# rxfail\r\n\r\n# master\r\nset acc_hardware = NONE\r\nset mag_hardware = NONE\r\nset baro_hardware = NONE\r\nset min_check = 1024\r\nset max_check = 2000\r\nset serialrx_provider = FPORT\r\nset serialrx_halfduplex = ON\r\nset dshot_idle_value = 250\r\nset motor_pwm_protocol = DSHOT600\r\nset align_board_yaw = 270\r\nset beeper_dshot_beacon_tone = 3\r\nset yaw_motors_reversed = ON\r\nset deadband = 4\r\nset yaw_deadband = 4\r\nset frsky_vfas_precision = 1\r\nset vtx_channel = 7\r\nset vtx_power = 2\r\nset vtx_freq = 5860\r\n\r\n# profile\r\nprofile 0\r\n\r\n# rateprofile\r\nrateprofile 0\r\n```"},"comment":{"url":"https://api.github.com/repos/betaflight/betaflight/issues/comments/362941406","html_url":"https://github.com/betaflight/betaflight/issues/5120#issuecomment-362941406","issue_url":"https://api.github.com/repos/betaflight/betaflight/issues/5120","id":362941406,"user":{"login":"jflyper","id":14850998,"avatar_url":"https://avatars0.githubusercontent.com/u/14850998?v=4","gravatar_id":"","url":"https://api.github.com/users/jflyper","html_url":"https://github.com/jflyper","followers_url":"https://api.github.com/users/jflyper/followers","following_url":"https://api.github.com/users/jflyper/following{/other_user}","gists_url":"https://api.github.com/users/jflyper/gists{/gist_id}","starred_url":"https://api.github.com/users/jflyper/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/jflyper/subscriptions","organizations_url":"https://api.github.com/users/jflyper/orgs","repos_url":"https://api.github.com/users/jflyper/repos","events_url":"https://api.github.com/users/jflyper/events{/privacy}","received_events_url":"https://api.github.com/users/jflyper/received_events","type":"User","site_admin":false},"created_at":"2018-02-04T21:30:05Z","updated_at":"2018-02-04T21:30:05Z","author_association":"NONE","body":"You can try #5076."}}
