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).

Oh, I connect the pin between 51822 and cp2102 as(P0.08= RTS, P0.09=TXD, P0.10= CTS, P011= RXD), Thr probable reason is I havn't a rigtht hex file for nrf51822.
