Doens't seems that it's supported. Please use one of the nRF5 DK or dongle for the purpose.

I am planning to use CP2102 (USB to UART) and RF-BM-ND06 NRF52840 bluetooth module for sniffing BLE packets .

Or as an alternative for Nordic Bluetooth USB dongle.

But after connecting the hardware to the Nordic NRF Connect Desktop Application I am getting error as "Unsupported device with serial number '0001' and traits".

Let me know if there are any steps I am missing.

I'm not sure what are you planing to do. Are you planing to use them as the back end for nRF Connect app or you are planing to use as ble-sniffer application ?

Anyway, please create a new case for that.

I am using a combination of CP2102 and RF-BM-ND06 NRF52840 bluetooth module for ble-sniffer application.

But in the nordic connect app I am getting the error Unsupported device with serial number '0001' and traits ["serialport"]. [Windows 10 OS ad I have installed the CP2102 drivers]

@Chenyu: Please test UART communication using the UART example code. Also please provide schematic or a photo of your setup.

Did anyone mention that this would be so much easier of you just use the standard, ready-made dongle - so that we wouldn't be having to try to remotely work out what thing(s) you've omitted and/or done wrong in your design and/or implementation... ?

Yeah, I obey your way, connect the right pin and download right firmware. But when I connected com4(cp2102) in PC master control panel, It remind "no response from master emulator",and I try to exchange RTS/CTS,TXD/RXD, and the reminder is still appear.

If you want to use with Master Control Panel, you need to flash MEFW_nrf51822_0.11.0_firmware_1M.hex from C:\Program Files (x86)\Nordic Semiconductor\Master Control Panel\3.10.0.14\firmware\pca10000 folder

Yeah,What you thought is right, I just want to use these two IC(nrf51+cp2102) to connect PC Master Control Panel as a usb dongle.

@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.

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.

Hi Chenyu,

You need to tell me how you connect the nRF51822 to the cp2102. The hex files you mentioned were not for the nRF51 but the interface CPU on the dev kit that you don't have.

And I agree with Awneil, it's easier that you get started with a DevKit.

chenyu — Thu, 14 Apr 2016 07:39:27 GMT

I havn't the right HEX file for 518222 to be a dongle.I 've try flash"J-Link OB-SAM3U128-V2-NordicSemi 160212" or "nrf51822aa_atsam3u2c_if_mbed_V0218_19022015" or "nrf51822aa_atsam3u2c_if_mbed_V0219_02022016"But all of the can't be recognized by MCP software,and give a notice of "no response from master emulator". Can you provide a right Hex file? Is a softdevice needed befor flash dongle hex file?

And, of course, with a Dev Kit you have Support!

awneil — Wed, 13 Apr 2016 12:29:51 GMT

So many things to miss or get wrong - that's why you really should start with a Dev Kit!

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).

RE: Can nrf51822+cp2102 set as a USB dongle

awneil — Wed, 13 Apr 2016 08:02:51 GMT

I would strongly suggest that you do get a dongle and dev board to start with.

Use them to gain sufficient experience to enable you to answer this question!

That way, you will have known-good hardware, and will be able to use all the Nordic examples and tools - without having to worry that any problems are due to issues in your custom design and/or assembly.
