# Known Issues and Limitations

This is a list of known issues and limitations at the time of release. An
updated list can be found on the online documentation.

* Firmware update
  * The software update package must be located in the root level of the
    update media (subfolders are not yet supported).
* Cloud Connector
  * Remote file system management fails with long file names and paths
    (over 255 characters).
* Wireless
  * Performance of the wireless interface is reduced when using concurrent mode,
    as the wireless interface is shared between several different
    functionalities.
  * When using wireless concurrent mode, Digi recommends you keep the different
    modes on the same frequency channels. For example, when configuring access
    point mode on channel 36 in the 5GHz band, connect to the same channel both
    in station mode and Wi-Fi direct so that the radio performance is optimized.
  * When working as an access point, DFS-capable channels in the 5GHz band are
    not supported.
  * For P2P connections Digi recommends "Negotiated GO" modes. The QCA6564
    devices (ConnectCore 6UL and ConnectCore 8M Nano) fail to join autonomous
    groups.
* Trustfence is not yet supported on the ConnectCore 8M Nano.

## ConnectCore 8M Nano

* ConnectCore 8M Nano System-on-Module (SOM)
  * CPU wake-up sources are not yet supported
* ConnectCore 8M Nano DVK
  * The maximum bitrate for CAN interface is 125 Kbits/s. This is a software
  limitation from the CAN controller.

## ConnectCore 8X

* i.MX8QXP Processor
  * GPU maximum performance reduced. The maximum frequency targets are 850 MHz
    for the shaders and 700 MHz for the core. However, in this hardware release
    the maximum frequency is limited to 650 MHz for the shaders and 600 MHz for
    the core, with the corresponding performance reduction. These targets will
    be met in future releases of the hardware.
  * BSDL operation is not supported. It will be available in future releases
    of the hardware.

## ConnectCore 6UL

* ConnectCore 6UL System-on-Module (SOM)
  * The UART connected to the Bluetooth chip on early versions of the ConnectCore
    6UL system-on-module (hardware version < 4) cannot properly execute flow
    control. To work around this issue, UART1 of these SOM versions has been
    configured to operate at 115200 bps and without hardware flow control,
    reducing the maximum throughput of this interface.
  * The QCA6564 wireless chip does not support Wake On Wireless LAN.
