Thanks for letting us know. :)

Thanks a lot for the valuable information you provided. I solved the issue by changing the UART TX, RX, CTS, and RTS pin numbers. The UART pins previously used were for integrating a motion sensor using the SPI peripheral

Hello,

''but the more confusing thing is that the same code works perfectly on the nRF52832 PCA10040 development board'' Do you mean it works on our board but not on your custom board? Then it would be a problem with hardware design.

I can see my colleague Jared is helping you there. It is better to get help from one platform. We have summer vacation time here. So, there is some unwanted delay. You will get answer next week.

hi , I am getting an error code 4 indicating a memory issue, and then after that, I get a fatal error. I integrated the timer peripheral into the app_ble_uart example project, but the more confusing thing is that the same code works perfectly on the nRF52832 PCA10040 development board .

I raised a ticket regarding my issue, which you can see on the link below. However, my issue has not been resolved

Hello,

[quote user="siltvm"]We are testing with the BLE UART example from SDK 17.0.2, and it is not working[/quote]

What is the error you are getting?

Is it your custom application?

hello jpily111 , I'm also implementing BLE after making a custom NRF52810 board. We are testing with the BLE UART example from SDK 17.0.2, and it is not working. The Bluetooth connection disconnects after a few seconds from establishing a connection and indicates a fatal error. I am using an internal oscillator like yours. Can you provide the steps you followed to build and flash the code?

Edit: looks like this is what you have, but try placing at very top of sdk_config.h

Try this at top of sdk_config.h, clock accuracy must be 500ppm for internal RTC (no 32kHz crystal):

// NO_32_KHZ_CRYSTAL
#define NRFX_CLOCK_CONFIG_LF_SRC         0
#define CLOCK_CONFIG_LF_SRC              0
#define NRF_SDH_CLOCK_LF_SRC             0
#define NRF_SDH_CLOCK_LF_RC_CTIV        16
#define NRF_SDH_CLOCK_LF_RC_TEMP_CTIV    2
#define NRF_SDH_CLOCK_LF_ACCURACY        1 // <1=> NRF_CLOCK_LF_ACCURACY_500_PPM

그리고 XCl1 (xtal1), xcl2 (xtal2)가 제대로 납땜 된 것 같습니다. 검증은 Arduino IDE를 사용하여 테스트되었습니다. 크리스탈이 제대로 납땜되어 있기 때문에 Serial.print가 터미널에 제대로 인쇄됩니다. 이것은 크리스탈이 32mhz를 mcu 측에 제대로 전달하고 있음을 의미합니다

Thank you for your answer. My current account is locked, so I'm replying to you by creating another ID.
I misconfigured sdk.
pages xl1 and xl2 are not used because they refer to the reference data sheet circuit diagram.
I don't have crystals for xl1 and xl2 32,768 RTC. I'm using them now as pins for other uses instead.
Based on this, I have configured SDK_config with the current circuit diagram. Current
1. 1. NRFX_CLOCK_Activation 1
2. 2. 2. NRFX_CLOCK_CONFIG_LF_SRC 0
3. 3. NRF_CLOCK_Activation 1
4. 4. 4. LOCK_CONFIG_LF_SR 0
5. 5. 5. 5. NRF_SDH_CLOCK_LF_SRC 0
6. 6. 6. 6. NRF_SDH_CLOCK_LF_RC_CTIV 16
7. 7. 7. 7. NRF_SDH_CLOCK_LF_RC_TEMP_CTIV 2
8. 8. NRF_SDH_CLOCK_LF_Accuracy 1
I knew this was wrong.

I've configured it to use xtal. I don't know if it's correct, but..
I would appreciate it if you could let me know how to configure it based on the current circuit diagram. After doing sdk_config as I currently thought

When you build and run after the configuration
Power_management_init(); does not go to the next.

Hello,

SDK configuration looks good as you dnt have external LF.

''The code seems to be working normally, but Bluetooth is not advertising.'' - It seems like high frequency crystal issue. Did you solder XC1 and XC2 to the board properly?
