Hello,
In the example given in snip.uart I use the UART1 and UART2 simultaneously, the first one is used for debugging while the second one is used for communication with a device. I correctly receive the data sent by UART 1 to UART, however, I am unable to send data using UART2.
The platform used is the BCM943362 with the SDK 2.4.1.
Thank you in advance for your help

What is your platform? Is it BCM943362WCD4?
About BCM943362WCD4,
only PA2/PA3 (as WICED_GPIO_3/WICED_GPIO_4) can be used for WICED_UART_2 as USART2.
PA0/PA1 may be configurable as UART4.

I have use SDK2.4.1 UART example too, it works fine.
Which EVB you're using?
How to connect to uart?
Please double check pin define in datasheet.

Hello,
Thank you for your reply.
The EVB used is the BCM9WCD1, I have checked the datasheet, the Tx/Rx are attached to the pins 2/3. However, I didn't connect the CTS RTS pins. Any idea ?
Regards

If you use SDK 2.4.1 , please check
~/include/platforms/YOUR_BOARD_TYPE/platform.h
~/Wiced/Platform/YOUR_BOARD_TYPE/platform.c
find out WICED_UART_1 / WICED_UART_2 : .pin_tx / .pin_rx , and which pin mapping in platform.h.
Each pin have mux-function, so make sure you plug-in right pin.
If still not work, it should be platform pin definition issue,
contact you EVB manufacturer to get the right platform file patch.
I use SPIL EVB, and you? USI? inventek?

Hello,
The eval board used is BCM9WCD1, this board has only one UART. I tried to use the WICED_GPIO_8 and WICED_GPIO_7 into UART2 but still have the same problem ...

Hello dmiya,
The platform used is the BCM943362WCD4.
I use now PA2/PA3 for UART2 and it is working perfectly. Thank you so much for help
