# VOXL 2 J18 port for External FC Source: https://forum.modalai.com/topic/4850/voxl-2-j18-port-for-external-fc Category: General Questions (https://forum.modalai.com/category/2/general-questions) Posted: 2025-11-04 07:31:33 UTC by Jetson Nano Replies: 14 · Views: 1290 ## Jetson Nano · 2025-11-04 07:31:33 UTC Hey @Vinny @Eric-Katzfey , guys I am trying to use the J18 port on voxl 2 for connecting the external FC ( flight core v2). While I try to run it , the voxl-mavlink-server is throwing error. I assigned the autopilto_uart_bus to 12 as mentioned in the documentation. ``` voxl2:/$ voxl-mavlink-server loading our own config file ================================================================= Parameters as loaded from config file: primary_static_gcs_ip: 192.168.168.2 secondary_static_gcs_ip: 192.168.8.11 onboard_port_to_autopilot: 14556 onboard_port_from_autopilot: 14557 gcs_port_to_autopilot: 14558 gcs_port_from_autopilot: 14559 en_external_uart_ap: 1 autopilot_uart_bus: 12 autopilot_uart_baudrate: 921600 autopilot_mission_delay_start: -1 autopilot_mission_delay_sound: 0 autopilot_mission_notif_dur: 0.10 udp_mtu: 500 gcs_timeout_s 4.50 en_external_ap_timesync: 1 en_external_ap_heartbeat: 1 ================================================================= Sending library name request: libslpi_qrb5165_io.so Sending initialization request Received standard error event SNS_STD_ERROR_NOT_SUPPORTED Couldn't configure flight_controller sensor ERROR: fc_sensor_initialize failed ERROR: Failed to initialize slpi ERROR: Encountered error while initializing bus 12 ERROR: Unable to configure bus 12 (baudrate 921600) with voxl_io Stopping autopilot io module Stopping gcs io module Stopping pipe io module closing remaining client pipes closing remaining server pipes Removing PID file exiting ``` ## Reply by Jetson Nano · 2025-11-04 07:36:11 UTC the error mentioned above was caused by the voxl-px4 server, once I disabled it was solved. Still I was not able to see the data from the external FC ``` voxl2:/$ voxl-mavlink-server loading our own config file ================================================================= Parameters as loaded from config file: primary_static_gcs_ip: 192.168.168.2 secondary_static_gcs_ip: 192.168.8.11 onboard_port_to_autopilot: 14556 onboard_port_from_autopilot: 14557 gcs_port_to_autopilot: 14558 gcs_port_from_autopilot: 14559 en_external_uart_ap: 1 autopilot_uart_bus: 12 autopilot_uart_baudrate: 921600 autopilot_mission_delay_start: -1 autopilot_mission_delay_sound: 0 autopilot_mission_notif_dur: 0.10 udp_mtu: 500 gcs_timeout_s 4.50 en_external_ap_timesync: 1 en_external_ap_heartbeat: 1 ================================================================= Sending library name request: libslpi_qrb5165_io.so Sending initialization request Successfully opened bus 12 at baudrate 921600 starting qrb5165 external AP receive thread Adding primary GCS IP address from conf file to list: 192.168.168.2 Added new UDP connection to 192.168.168.2 Adding secondary manual gcs IP address to udp connection list: 192.168.8.11 Added new UDP connection to 192.168.8.11 Init complete, entering main loop ``` ## Reply by Jetson Nano · 2025-11-04 10:12:30 UTC (in reply to Jetson Nano) @Jetson-Nano now it is getting data from fc , it was a issue with baudrate, the J18 port can not handle 3000000 baudrate. still i am facing an issue, where the QGC is not getting connected, the qgc is loading,then getting disconnected, again regaining connection this is going in a loop. I tried increasing the udp_mtu still no change, same behaviour. The error is mentioned below. ``` Sending topic message --- msg_id: 1033 --- topic name: uart_data Sending topic message --- msg_id: 1033 --- topic name: uart_data Sending topic message --- msg_id:

Can you try a lower baudrate, like 57600, and see if that works better? ## Reply by Jetson Nano · 2025-11-04 18:27:33 UTC (in reply to Eric Katzfey) @Eric-Katzfey I tried lower baudrate also, the behaviour is similar. ## Reply by Eric Katzfey (ModalAI staff) · 2025-11-04 21:31:39 UTC (in reply to Jetson Nano) @Jetson-Nano Do you still get those messages from voxl-mavlink-server about dropped packets from external AP? ## Reply by Eric Katzfey (ModalAI staff) · 2025-11-04 21:32:46 UTC (in reply to Jetson Nano) @Jetson-Nano Are you using WiFi to connect with QGC? ## Reply by Jetson Nano · 2025-11-05 10:50:33 UTC (in reply to Eric Katzfey) @Eric-Katzfey yes I still had that messages popping up ## Reply by Jetson Nano · 2025-11-05 10:51:42 UTC (in reply to Eric Katzfey) @Eric-Katzfey No I was using the Microhard module. Irrespective of the communication module, these many time should the sysid change and the packet lose should not occure, right? ## Reply by Jetson Nano · 2025-11-05 12:55:05 UTC (in reply to Eric Katzfey) @Eric-Katzfey I changed the Mavlink version to what you had mentioned here, I felt the errors were similar [Link](https://forum.modalai.com/post/24270) **this is when baudrate is 57600** ``` voxl2:~$ voxl-mavlink-server loading our own config file ================================================================= Parameters as loaded from config file: primary_static_gcs_ip: 192.168.168.200 primary_static_gcs_ip_port: 14550 secondary_static_gcs_ip: 192.169.168.2 secondary_static_gcs_ip_port: 14550 onboard_port_to_autopilot: 14556 onboard_port_from_autopilot: 14557 gcs_port_to_autopilot: 14558 gcs_port_from_autopilot: 14559 en_external_uart_ap: 1 autopilot_uart_bus: 12 autopilot_uart_baudrate: 57600 autopilot_mission_delay_start: -1 autopilot_mission_delay_sound: 0 autopilot_mission_force_restart: 0 autopilot_mission_notif_dur: 0.10 udp_mtu: 0 gcs_timeout_s 1.00 en_external_ap_timesync: 1 en_external_ap_heartbeat: 1 ================================================================= Sending library name request: libslpi_qrb5165_io.so Sending initialization request Successfully opened bus 12 at baudrate 57600 starting qrb5165 external AP receive thread Adding primary GCS IP address from conf file to list: 192.168.168.200:14550 Added new UDP connection to 192.168.168.200:14550 Adding secondary manual gcs IP address to udp connection list: 192.169.168.2:14550 Added new UDP connection to 192.169.168.2:14550 Init complete, entering main loop CONNECTED to GCS at 192.168.168.200:14550 Waiting to detect autopilot sys id...

Jetson Nano) @Jetson-Nano Looks like you are never receiving anything FROM the AP. Only sending stuff TO it. Can you put an oscilloscope on the RX / TX UART lines to see what the traffic looks like. For some reason it doesn't seem like the UART is setup properly on either the FC or the DSP so with an oscilloscope you can better see what is going on. ## Reply by Jetson Nano · 2025-11-07 14:35:29
