Already solved it because the speed in putty i set 15200. Not 115200

Hi,

If you want to use the terminal tool to see the log, please add the following setting in the sdk_config.h

// <e> NRF_LOG_BACKEND_UART_ENABLED - nrf_log_backend_uart - Log UART backend
//==========================================================
#ifndef NRF_LOG_BACKEND_UART_ENABLED
#define NRF_LOG_BACKEND_UART_ENABLED 1
#endif
// <o> NRF_LOG_BACKEND_UART_TX_PIN - UART TX pin 
#ifndef NRF_LOG_BACKEND_UART_TX_PIN
#define NRF_LOG_BACKEND_UART_TX_PIN 6
#endif

// <o> NRF_LOG_BACKEND_UART_BAUDRATE  - Default Baudrate
 
// <323584=> 1200 baud 
// <643072=> 2400 baud 
// <1290240=> 4800 baud 
// <2576384=> 9600 baud 
// <3862528=> 14400 baud 
// <5152768=> 19200 baud 
// <7716864=> 28800 baud 
// <10289152=> 38400 baud 
// <15400960=> 57600 baud

#ifndef NRF_LOG_BACKEND_UART_BAUDRATE
#define NRF_LOG_BACKEND_UART_BAUDRATE 30801920
#endif

// <o> NRF_LOG_BACKEND_UART_TEMP_BUFFER_SIZE - Size of buffer for partially processed strings. 
// <i> Size of the buffer is a trade-off between RAM usage and processing.
// <i> if buffer is smaller then strings will often be fragmented.
// <i> It is recommended to use size which will fit typical log and only the
// <i> longer one will be fragmented.

#ifndef NRF_LOG_BACKEND_UART_TEMP_BUFFER_SIZE
#define NRF_LOG_BACKEND_UART_TEMP_BUFFER_SIZE 64
#endif

// </e>

Also, enable NRF_LOG_ENABLED as

// <e> NRF_LOG_ENABLED - nrf_log - Logger
//==========================================================
#ifndef NRF_LOG_ENABLED
#define NRF_LOG_ENABLED 1
#endif

I already upload it to gist at github. Here the link https://gist.github.com/zawawimanja/0df14f7bcf295656a04f5fc58959233b

Hi,

[quote user="ox00"]#define HCI_UART_BAUDRATE 30801920 in sdk_config.h [/quote]

In the sdk_config.h, 30801920 means 115200 baud.

[quote user="ox00"]in putty is 115200. Do I need to change the speed in sdk_config.h ?[/quote]

The setting should be fine on the both sides.

Could you share the sdk_config.h?

#define HCI_UART_BAUDRATE 30801920 in sdk_config.h

in putty is 115200. Do I need to change the speed in sdk_config.h ?

Hi,

What is your speed of putty and the NRF_LOG_BACKEND_UART_BAUDRATE value in the sdk_config.h?

[quote user="ox00"]Does not make sense because when installing at other computer is ok.[/quote]

I am not confident to have a solution. If the issue only happened to the specific computer instead of others, I would suggest using others.

What example are you using?

Do you have nRF52840DK? If so, could you run the BSP Example? Also, follow the setting:

Start a terminal emulator like PuTTY and connect to the used COM port with the following UART settings:

Baud rate: 115.200
8 data bits
1 stop bit
No parity
HW flow control: None

Do you also see the same issue while executing the example?

-Amanda H.

Does not make sense because when installing at other computer is ok. already unistall & reinstall back nothing work.

another post recommends checking the settings in sdk_config.h also.

everthing is right. Dont know what is wrong.Maybe I will uninstall putty and reinstall back.

Does it work at all? I'd check that your Speed is set right (and data and stop bits).
