add another UART on usbd_ble_uart example

[hazakomura]

Hi !

I would like to implement UART on EVA board using MBN52832 SDK.
Example usbd_ble_uart uses one UART for LOG printf.
Please tell how to implement another UART on that project to
communicate with our product device.

regards

Is that a 3rd-party SDK ?

Hi!

that is nRF5_SDK_17.0.0_9d13099

thanks

So is this the module you're talking about https://wireless.murata.com/mbn52832.html ?

Remember that it is an independent 3rd-party product - so you can't assume that people will just automatically know what you're referring to. Always helps to give a link.

Anyhow, that uses an nRF52832 - and the nRF52832 has only one UART:

Some options:

1. Move your debug logs from the UART to RTT;
2. Add an external hardware UART
3. Use some other interface (eg, SPI, I2C) for your "product device"
4. Implement a soft UART
