Enable UART communication for CC2540 in HostTestAPP program

Vijay Belurkar

Other Parts Discussed in Thread: CC2540

Hi everyone,

I'm using cc2540 mini development kit which includes the keyfob and usb dongle.

I'm able to send commands through Btool as well as any other serial terminal ( real term and Brays terminal) to USB dongle and get response in hex format from the keyfob.

But how do we enable UART communication instead of USB in the dongle? That is I want to use the physical UART interfaced with some microcontroller to send the same commands that I'm sending through USB port.

Since the USB dongle is flashed with HostTestAPP program for CC2540USB, What changes are to be done to enable UART communication instead of USB.

Kindly help with this...!!

Hi Vijay,

In the HostTestApp IAR project workspace, there is a project config for "CC2540UART_PM". This is a non-USB implementation and should be a good reference for adding UART. Note that CC2540UART_PM is not designed to run on the CC2540USB dongle.

Best wishes

Hello sir,

I'm not able to find the configuration CC2540UART_PM in the IAR project workspace. I'm using BLE-CC254x-1.4.0 stack.

I can see only the above configurations for hosttestapp project. Could you please tell me which one of the above configuration gives a better reference for adding UART.

And is it possible to use this configuration on keyfob if not with USB dongle..?

Thanks

Vijay

Hi Guys,

Any progress on this?

I also want to implement a UART version of the HostTestApp.

It should be possible since we have it working on the CC2540EM. See here for ref:

Hi,

I want to implement a UART version of the HostTestApp. I tried to use the CC2540EM version but when i send HCI command (DeviceInit), i don't have the feedback of the Soc via the UART ports. Have you finally found how to implement UART version of this one?
