The XSR receiver outputs RSSI onto CH8 (Betaflight AUX4) automatically.\r\n\r\nWhat happens is that the value of the AUX4 on the receiver tab is stuck on 1971 (or maybe 1791?), even if I turn the transmitter off. \r\nI have all the endpoints set to 1000-1500-2000, +-4.\r\n\r\nI tried to set an output in the mixer on my x9d, but then found a video saying that the xsr receivers don't need it done that way. It's just done automatically through CH8 (AUX4) . I have telemetry coming from my FC into the X9D and can see the RSSI. When I had the RSSI set as an output on CH8 in my mixer, there was no change to the CH8 value in the receiver tab in BF.\r\n\r\nIf I start with the FC connected to BF, but with the X9D turned off, then AUX4 is at 1500. When I switch the X9D on, AUX4 goes up to 1971.\r\n\r\nIf I do a \"set rssi_invert = ON\", there is no change.\r\n\r\n```# version\r\n# Betaflight / FRSKYF4 (FRF4) 3.2.4 Jan 10 2018 / 22:49:20 (90d32fd56) MSP API: 1.36\r\n\r\n# name\r\nname Purple\r\n\r\n# resources\r\nresource MOTOR 5 NONE\r\nresource CAMERA_CONTROL 1 A01\r\n\r\n# mixer\r\n\r\n# servo\r\n\r\n# servo mix\r\n\r\n\r\n# feature\r\nfeature TELEMETRY\r\nfeature AIRMODE\r\nfeature ANTI_GRAVITY\r\nfeature DYNAMIC_FILTER\r\n\r\n# beeper\r\nbeeper -ON_USB\r\n\r\n# map\r\n\r\n# serial\r\nserial 2 8192 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 0 1400 2100\r\naux 1 1 0 1800 2100\r\naux 2 13 1 1800 2100\r\n\r\n# adjrange\r\n\r\n# rxrange\r\n\r\n# vtx\r\n\r\n# rxfail\r\nrxfail 3 h\r\n\r\n# master\r\nset acc_trim_roll = 10\r\nset min_check = 1015\r\nset motor_pwm_protocol = DSHOT600\r\nset failsafe_delay = 5\r\nset failsafe_kill_switch = ON\r\nset pid_process_denom = 1\r\nset osd_cap_alarm = 1500\r\nset osd_tim1 = 2561\r\nset osd_tim_2_pos = 33\r\nset osd_throttle_pos = 225\r\nset osd_crosshairs = 200\r\nset osd_ah_sbar = 200\r\nset osd_ah_pos = 200\r\nset osd_current_pos = 385\r\nset osd_gps_speed_pos = 218\r\nset osd_gps_lon_pos = 82\r\nset osd_gps_lat_pos = 65\r\nset osd_gps_sats_pos = 51\r\nset osd_home_dir_pos = 302\r\nset osd_home_dist_pos = 303\r\nset osd_compass_bar_pos = 266\r\nset osd_altitude_pos = 247\r\nset osd_pid_roll_pos = 0\r\nset osd_pid_pitch_pos = 0\r\nset osd_pid_yaw_pos = 0\r\nset osd_debug_pos = 1\r\nset osd_power_pos = 321\r\nset osd_pidrate_profile_pos = 345\r\nset osd_avg_cell_voltage_pos = 76\r\nset osd_pit_ang_pos = 257\r\nset osd_rol_ang_pos = 289\r\nset osd_nheading_pos = 311\r\nset osd_nvario_pos = 279\r\nset osd_esc_tmp_pos = 82\r\nset osd_esc_rpm_pos = 83\r\nset osd_stat_max_spd = OFF\r\nset osd_stat_bbox = OFF\r\nset osd_stat_endbatt = ON\r\nset osd_stat_bb_no = OFF\r\nset osd_stat_tim_1 = ON\r\nset osd_stat_tim_2 = OFF\r\nset vcd_video_system = 2\r\nset camera_control_key_delay = 125\r\n\r\n# profile\r\nprofile 0\r\n\r\n\r\n# rateprofile\r\nrateprofile 0\r\n```\r\n\r\nhttps://www.frsky-rc.com/wp-content/uploads/2017/07/Manual/XSRF4O/01140067-XSRF4O.pdf\r\nhttps://img.banggood.com/file/products/20160119004828XSR(2).pdf\r\n\r\nHoping somebody here can help.
