@Alex-Kushleyev What you mentioned is modifying the ESC telemetry rate from the PX4 side. I think what @hanzichi was looking for is the rate at which the ESC produces ESC_PACKET_TYPE_FB_POWER_STATUS packet to PX4. I would be great if this was a parameter in the voxl-esc-tools that are uploaded directly to the esc

@Alex-Kushleyev
Sounds good I'll give it a shot. Thanks!

For my application it would be preferred. I saw where it is in the PX4 driver - I just was hesitant to make the changes and wanted confirmation from the ModalAi team that there isn't any issues on the ESC side if I were to make the change.

Thanks for the speedy reply and I'll proceed on if there is no issues.

Hi,

Model: VOXL ESC Mini 4-in-1 with Built-in Power Module
Firmware: modalai_esc_firmware_m0129_3_v0_39_RC10_eb6fb500.bin

I'm not using all of the ESC outputs and I'd have set them to disable.
Although, the current firmware on the PX4 does not support the disable feature. I was wondering if there was a particular reason that this capability does not exist?

Update:

It was an issue on my end regarding the baud-rate configuration.

All is good.

Hi,

The below is my setup:
Model - 4in1 micro esc m0129
Firmware - 39, hash fb6fd95
Bootloader - 184, hash 10bf24c8

modal_io.cpp
parse_response()
qc_esc_packet_process_char() - returns ESC_ERROR_BAD_HEADER

I was wondering if there is a interface control document available for devs? Also has the byte communication changed in this version of ESC firmware?

Thanks!

Hi,

I was wonder when you guys will share your esc control firmware on your technical documents?

Snapshot is from the following document:

    https://docs.modalai.com/modal-esc-v2-manual/#esc-parameters

Thanks!

@Alex-Kushleyev

Appreciate all the help! I can confirm the new firmware verifies the parameters successfully.

Hi,

Just wanted to follow up if anyone was able to recreate this issue or can see something that might be off with my setup steps?

Thanks

Hi,

I'm currently working setting up the VOXL ESC Mini 4-in-1 with Built-in Power Module (M0129).

Following the steps on this link:
https://docs.modalai.com/modal-esc-v2-manual/

I've updated the firmware using the binary found in:
/voxl-esc/voxl-esc-tools/firmware/modalai_esc_firmware_m0129_3_v0_39_RC4_c0bf9200.bin

I've verified that worked with the voxl-esc-scan.py file

Problem:
I uploaded the esc_params_generic_m0129.xml using voxl-esc-upload-params.py. Then I run a voxl-esc-verify-params.py and get the following output

I haven't modified the parameters file and would like to know if the generic params is missing a parameter that needs to be updated? Also is there a source where the developers can see the necessary parameters needed to configure this esc board?

Let me know if there is other information you need from me to help troubleshoot.

Thanks
