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 fail to join autonomous groups.
- ConnectCore 93 System-on-Module (SOM)
- Trustfence
- It is not possible to close a device using U-Boot v2024.04 for Secure boot on a device with CPU revision A0. However, it is possible to boot v2024.04 signed images on an already closed device.
- Trustfence
- 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.
For support questions please contact Digi Technical Support:
When you contact Digi Technical Support, include important system details and device information to help Digi resolve the issue more quickly.
- In the device, run the command 'sysinfo'. This generates the following file: /tmp/<current timestamp>.txt.gz.
- Attach the <current timestamp>.txt.gz file to your support ticket.
