  • Meaning of esc_state for M0129 Mini 4-in-1 ESC
    S schew

    Hi all,
    I would like to ask what the esc_state parameter in esc_status means. Based on the PX4 documentation at https://docs.px4.io/main/en/msg_docs/EscReport, this state is dependent on vendor but I cannot find any mention of it on ModalAI's ESC documentation pages.

    Any advice would be appreciated.

  • Turning off ESC regenrative braking for calibration
    S schew

    Hi, I would like to calibrate my M0129 ESC using a power supply, but I understand it's advised not to do so as this can damage the ESC. Would thus like to ask if the regenerative braking can be turned off only for ESC calibration.

    I did notice that there is a brake_to_stop param in the parameters file, however it is unclear whether a 1 or 0 parameter deactivates the regenerative braking.

  • Serial communication with Sierra Wireless EM9291
    S schew

    I have configured the standard software with voxl-configure-modem; it works and I can connect to the internet, however the APN is different as I am not based in the US.
    I am planning to use the AT commands to configure some of the more specific parameters of the modem e.g. setting bands, etc.

  • Serial communication with Sierra Wireless EM9291
    S schew

    Hi,

    I am using a Sierra Wireless EM9291 modem with VOXL 2 and the carrier board, which I want to connect to over serial to send AT commands.

    I cannot find the device path in /dev, ls /dev/ttyUSB* returns no such file or directory. How should I communicate with the modem?
