Can nrf51822+cp2102 set as a USB dongle

[chenyu]

Hi: I have no dongle or any other Dev board such as PCA10031. Can I use nrf51822 and cp2102 as a usb dongle to work with MCU of PC? If the answer is yes, what should I do? Thank you very much!

Hi Chenyu,

I think should be possible. Make sure you have the driver for the USB-UART dongle (cp2102), then make sure you connect the same UART pins as with our Dongle and DK kit (P0.08= RTS, P0.09=TXD, P0.10= CTS, P011= RXD).

@Chenyu: Sorry that I thought you wanted to use the chip with the PC Master Control Panel. If not, then you are free to connect any pins. You can test with the UART example in the nRF5 SDK. Note that you need to have the driver for the cp2102 so that it opens a virtual comport on your PC.
