Hi Nichol,

It is not clear on your photo, is there a jumper between J10(5-6)(TX) and J10(7-8)(RX)?

Pong

[Nichol]

Hi,Pong,

the jumper both have been taken off.

[ChiP_16]

Hi Nichol,

You need jumpers between J10(pin 5 and pin6)(TX) and J10(pin7 and pin8)(RX).

Refer to schematic for details.

This pin now connected. The same result.

Hi Nichol,

There are 2 com ports for the board. Please use the WICED Peripheral UART port. I have also attached a photo of the board with the jumpers. I am able to run the HAL_UART application without issue.

Hi Pong,

The Hardware and software config are as follows,should I set the Bluetooth address first?

[ChiP_16]

Hi Nichol,

HAL_PUART does not involve Bluetooth, no need to set Bluetooth address. Your settings are similar to mine.

Did you program the board?

Pong

Hi Nichol,

The application code sent out some text on reset. It is also not received on your COM program. I doubt you made any changes to device configuration. Anyway, I have attached the screenshot of mine for your reference.

Pong
