First time here? Check out the Tour!
I have an example combining BLE, UART and SPI in which I use RTT to watch the startup process. The SoC is nRF52 (BLE Nano2); building with armgcc. This works ok when JLink is connected. However, if I unplug the ... (more)
Hey, is there a possibility to connect two or more devices to RTT viewer?
It looks like system (laptop windows 7) is not supporting more than two windows of RTT viewer simultaneously. When I connect, third one, it disconnects, one of the two's.
Is there any way to connect four windows of ... (more)

We are using a nRF52840 (QIAAAA) on a custom board which replicates exactly the schematic used by the development kit (PCA10056). When using Segger RTT for debugging purposes, the board does not emit any BLE packets (no errors are reported ... (more)
ble_app_buttonless_dfu to get log with UART is possibly.
I want to change RTT log.
How can I do?
Board is nRF52-DK. SDK is nRF5_SDK_14.0.0_3bcc1f7.
Hi, I have problem with using printf() in SEGGER RTT.
I've read tutorial and others about SEGGER RTT printf() problem, but they didn't work.
When I use printf() in RTT and compile I got error like this:

Hi, I am running the ble_app_uart example from nRF5_SDK_14.0.0_3bcc1f7, and found that NRF_LOG_DEBUG() doesn't cause any log output. Although I have set #define NRF_LOG_ENABLED 1 and #define NRF_LOG_DEFAULT_LEVEL 4.
However, it's OK in the ... (more)
I am trying to test a combination of BLE central role, Thread with CoAP server and FreeRTOS on an nRF52840 using version 0.10.0 of nRF5-SDK-for-Thread.
I don't seem able to get RTT traces from any example based ... (more)
I have just updated the SEGGER Jlink tools to the latest version v6.18b.
Under Keil debbuging the J-Link RTT Viewer (or client) shows the initialization commands in an infinite loop (one after the other starting from the first ... (more)
I have tried to use sd_app_evt_wait() to sleep cpu, and use gpiote interrupt to wake up cpu from sleep. However, gpiote interrupt cannot wake up cpu. When I use __WFE(), gpiote interrupt can wake up cpu. And even if I ... (more)
HEllo I am having an error saying
Undefined reference to SEGGER_RTT_printf
I have looked into this post and tried it, however I am not able to fix it,I have defined
GLOBAL_DEBUG on my preprocessor settings but the linker seems ... (more)
Help please, I'm evaluating ble_app_uart (Central/Peripheral) but I don't understand how to disable the echo I have on the RTT USB VCP
When I send data from the UART, I got (PCA10056/10040) the data ... (more)
Currently developing on NRF52 sdk12
I want to be able to show time stamp minutes:seconds:miliseconds on my RTT viewer, when I print my data out from the uC. Any hits on how to do that?
I'm looking ... (more)
Currently developing on NRF52 sdk12 with a terminal
In my source code i have nrf_log_init(null), and this allows me to print stuff to the RTT viewer.
Now I want to be able to show time stamp minutes:seconds:miliseconds ... (more)
I installed the latest version of Jlink 6.16f. I connected my nrf52-dk and on opening the RTT viewer, I always need to specify the target device manually instead of it being detected automatically. I am also attaching a ... (more)
I am finding that the RTT Viewer is very unreliable at changing colour when sent commands from two different nRF52-DK boards. The text is coming out correctly, but the colours only change intermittently. I've tried dropping the ... (more)
I followed the RTT tutorial but When I try to BUILD the project I got this error. What is it?
Error: L6200E: Symbol SEGGER_RTT_WaitKey multiply defined (by segger_rtt_1.o and segger_rtt.o). Error: L6200E: Symbol SEGGER_RTT_WriteString multiply defined (by ...

Hello, Is it possible to get logs (RTT) from an application started by a bootloader? As of now I don't get anything after the bootloader has jumped to the application start address.
If I run the application separately it ... (more)
Hi, can you help me out please: I have followed https://devzone.nordicsemi.com/questi... and have configured as it shows.
NRF_LOG_INFO does not work however
What should i do?
I need to interact with two J-Link debuggers, connected to the same PC at the same time. I would then read and write data to the devices connected to the debuggers.
To send/receive the data, I was thinking ... (more)
