Uart implemntation

Dear NXP team,

I am using eatt central for receiving data over uart and printing through shell in teraterm but HAL_UartSendNonBlocking() but when I am using this function to print in teraterm it is not working how to implement uart in example code I have configure clock port and initialization

void UART1_Init(void)

{

hal_uart_config_t config;

config.baudRate_Bps = 921600;

config.enableTx = true;

config.enableRx = true;

CLOCK_GetIpFreq(kCLOCK_Lpuart1);

HAL_UartInit(LPUART1, &config);

can you please help me for the same.

Thanks and regards

Chetan

Hello Chetan

What SDK version are you using?

The example EATT Central already implements a UART communication,

The application behaves as a GAP central node. It searches for an EATT peripheral to connect to. After

connecting, it performs service discovery, initiates an EATT connection and configures indications on the

peripheral for services A and B. The Central reports the received service data and the steps taken during the

setup on a terminal connected to an UART port

For usage and response of the example please refer to Bluetooth Low Energy Demo Applications User’s Guide Chapter 5.4 EATT Central and 5.5 EATT Peripheral.

Could you help us confirm what is your response in teraterm and can you share this please?

HAL_UartSendNonBlocking is returning any status or response?

Could you help us describe all the modifications implemented in your code? As I don’t see the configurations in "HAL_UartSendNonBlocking", also if there is modifications implemented in the EATT_peripheral example?

Best Regards

Luis
