Offboard Mode not working with Pixhawk4 mini running latest Version of px4 firmware and mavros

Hello Sir. Firstly let me begin by thanking you for answering my doubt. Secondly, the tutorial you have on the website is a useful one.

Getting back to our discussion about my doubt,

  1. Yes I am sending the setpoints at 10Hz.
  2. How to check if I have time stamps encoded correctly for the setpoint messages?
  3. I am following the link you have attached for configuring the port for the companion computer. So from what I understood, let me try to summarize here (please correct me if I am wrong). The MAVlink is supposed to be configured for telem1 port of the pixhawk4 mini since I do not have telem2 port. So I will have to set the parameters as follows on the pixhawk using QGroundControl

MAV_1_CONFIG = TELEM1 (101)
Mav_1_MODE = ONBOARD (2)
MAV_1_RATE = 921600 baud.

Now, i am supposed to enter the rate in Bytes per second and 921600 is the baud rate. What is the conversion factor I should use to enter MAV_1_RATE? I will check rest of the settings and try running the example again. Thank you for your help.
