ESC Issue On SDK 1.0.0
-
Good afternoon,
I am having an issue where I cannot get ESC to work and props to spin on 1.0.0. When I am on 0.9, the blue indicator light on the ESC flashes and I am able to spin props. Once I upgrade to 1.0.0, the light does not flash anymore and I cannot spin props.
Is there something I need to do to setup the ESC on 1.0.0?
Thank you for the help,
John Nomikos.

@John-Nomikos-0 What do you get with
voxl-esc scan?It does seem to be detecting the ESCs with that command.
Strange that the blue light does not blink and spinning is not working on 1.0.0

To clear things up.
The ESC is not working when we arm. It does not spin with "actuators" tab.
The ESC only spins a motor when we issue a "voxl-esc" on the command line@wilkinsaf Please post the settings of all of the MODAL_IO_* parameters. E.g.

-fflag to force it. What happens if you don't use the force flag? Does it give you some errors? -

Definitely going to have to figure out a way to make PX4 provide an actual reason. Our ESC guru Alex thinks that the older ESC firmware you have defaults to a different baudrate than we are expecting in SDK 1.0.0 PX4. So he will respond later with the ESC parameter change that will allow them to have the same baudrate.

@Eric-Katzfey Thanks Eric.
I imagine we are going to have to connect the ESC to FTDI to laptop. Or is it possible to change this on VOXL2 terminal.

@wilkinsaf You should be able to do it directly on VOXL2 with voxl-esc.

Based on your description of the problem (when you switch from SDK 0.9 to 1.0.0, the ESCs start responding), it sounds like a mismatch in the UART baud rate in ESC and PX4 params. When going from 0.9 to 1.0.0 we have changed the baud rate for ESCs in PX4 params from 250K to 2M. Accordingly, we have updated the ESC params to 2M as well (ESC firmware and params are part of
voxl-escpackage). However, since you did not perform an ESC firmware / param update, your ESC is still running at 250K baud rate, but the latest PX4 is expecting 2Mbit.From your output of esc scan, this is confirmed:
INFO: ESC(s) detected on port: /dev/slpi-uart-2, baud rate: 250000You have several options:
- Change your PX4 param MODAL_IO_BAUD from 2000000 to 250000 in order to match what your ESC is currently using
- Update the ESC firmware and params while the ESC is connected to VOXL2 (with SDK 1.0.0 installed, which will have the latest
voxl-escpackage with latest firmware and params). Please see this post about updating firmware and params: https://forum.modalai.com/topic/2509/voxl-2-mini-with-mini-4-in-1-esc-no-battery-information/5 . Please note that if you are currently using non-standard ESC params, you will need to make a few updates to them in order to make them compatible with the latest parameter files. If that is the case, let me know, i can help.

Confirmed, changing the MODAL_IO_BAUD to 250000 fixed the problem for me. Thank you so much for the help!
