Using CDC ACM Command Line Transport Layer in usbd_cdc_acm_pca10056 example

[EvanJohnson]

Hey all,

I'm trying to replace the nrf_cli_uart transport layer with the CDC ACM equivalent (nrf_cli_cdc_acm), since I have an nrf52840 dongle and can't use the uart libraries. 

Generally, I'm just trying to get my hands around this because I think it would be useful in the future. Specifically, I'm trying to have an interface to eventually make the dongle a central bluetooth device, whose ble communication ports over to a host device via CDC ACM. 

So, I noticed multiple transport layers for the command line interface. The one for uart in the example is spun up as follows:

NRF_CLI_UART_DEF(m_cli_uart_transport, 0, 64, 16);
NRF_CLI_DEF(m_cli_uart,
            "uart_cli:~$ ",
            &m_cli_uart_transport.transport,
            '\r',
            4);

So, just wondering how to do something similar in the cdc acm transport layer. Looking in the source, it just looks like it's a queued event handler. Do I need to init the cdc acm layer and just let it do its thing? Again, just confused.

Hi,

You can refer to the CLI example, which supports the CDC ACM Command Line Transport. This example includes project files and a precompiled .hex file that demonstrates this on the nRF52840 dongle - pca10059 (the example documentation indicate that it only supports pca10056, but that is incorrect).
