Hi everyone:
I want to use UARTE on my FreeRTOS, but when I used the example(examples/peripheral/libuarte) in rtos, something went wrong.
First of all, I tested the example, and it looks like good. When I send slowly, the uart log is here.
and when I send quickly(every 4ms), the uart log is that.
But when I use the UARTE in FreeRTOS, It looks OK when sending slowly, but when I send it every 4ms(I need this frequency), the result is here.
I don't know what's wrong.
Best regards,
Lurn
Hi Einar,
I think something is wrong.
On the previous basis I used two nRF device to test my code.
No.1 use UARTE to receive data from PC and send the data to No.2 nRF device over esb.
No.2 use esb to receive data and send it to PC over UART.
When I tested it, I found that I can get the correct data from No.1 over esb, but when I send the data to PC over UART, Some data is wrong.
You can see the uart print, at 00283232 the data I send is
hex_str = '5AC48602030405060708090A0B0C0D0E0F0102030405060708090A0B0C0D0E0F'
but I loss the '02 03 04 05'
I can make sure that the data I received is correct. Because before I send it over UART, I print it by RTT, and it was ok.
printf("data_array = ");
for(int i = 0; i < index; i ++)
{
printf("%X,"data_array[i]);
}
err_code = nrf_libuarte_async_tx(&libuarte, data_array, index);
if(err_code != NRF_SUCCESS)
UART_PRINTF("nrf_libuarte_async_tx err_code = %d.", err_code);
APP_ERROR_CHECK(err_code);
Do you know what the problem is?
BR,
Lurn
