nRF5_SDK_16.0.0 board nRF52840 CLI uart problem.

[Eriksen]

Using nRF5_SDK_16.0.0 with the example: examples\ble_central_and_peripheral\experimental\ble_app_interactive. The terminal has been replaced by a PC application sending commands to the CLI over the serial link @ 115200 baud using hardware handshake. When sending long commands as: "gatt write request XX:XX:XX:XX:XX:XX YYYY 01 00 00 00 00 FF 03" the uart receive routine seem to loose the first part of the command and only passes the last "F 03" on to the cli_execute() function.  If I split the command in individual tokens and send them one-by-one with a short delay, everything is working as it should.  Looks like a problem in the uart receive functionality.

Hi,

Is this being tested with a nRF52840 DK with the on-board Segger chip acting as the USB UART bridge? In that case, it might be related to the JLink CDC bug mentioned here: https://docs.zephyrproject.org/1.12.0/tools/nordic_segger.html#disabling-the-mass-storage-device-functionality   (note: the power-cycle at the end is important. The change will not take effect otherwise)

Yes - Thanks a lot.  That made it work.
