Hi Guys,

Can someone explain, from where the variable BLE_UUID_OUR_SERVICE came? where it is defined or what is the value on this program?

line:   service_uuid.uuid = BLE_UUID_OUR_SERVICE;

Thanks for your answer!

With Regards,
Sreejith

I am using SDK v15 and got the following errors:

C:\BLE Projects\nRF5_SDK_15.3.0_59ac345\components\libraries\experimental_log\src\nrf_log_backend_rtt.c: No such file or directory
C:\BLE Projects\nRF5_SDK_15.3.0_59ac345\components\libraries\experimental_log\src\nrf_log_backend_serial.c: No such file or directory
C:\BLE Projects\nRF5_SDK_15.3.0_59ac345\components\libraries\experimental_log\src\nrf_log_backend_uart.c: No such file or directory

Did I miss anything?

I had a couple of problems with this which I have now solved and might be useful for others to know

1) With Segger SES, for logging to show up in the Debug Terminal, edit sdk_config.h so that NRF_LOG_BACKEND_RTT_ENABLED is 1.

2) Should be clear from the screenshots but not specifically mentioned, the nRF Connect mentioned is the PC desktop version not the iOS App. I kept finding irrelevant services shown in the iOS app, the Nordic UART service and characteristic, probably from a previous program running on the same nRF52-DK, even though this isn't anywhere to be found in this project. It turned out to be some sort of cached data in the iOS BT stack, because the same services also showed up in the LightBlue app. Disabling BT (white icon in the Control Centre) and re-enabling didn't fix it, but turning Bluetooth off in Settings, then back on, did. iOS version 12.4.1.

Thanks for the great tutorial. I have followed the steps and tried to understand most of the parts. I am using Segger Embedded studio and my target board is custom nRF52832 board along with nRF52 DK, there are two issues faced by me however:

Segger RTT viewer only shows print & write statements but no activity during connection & disconnection.
Even after adding step 5 & 6, app shows unknown service. It is displaying base UUID correctly, but there is no trace of OUR_SERVICE_UUID.

Let me know if I am missing something

Hi! I want to make my first code in my nrf51 dk (i have an PCA10028). I have experience with M0 and other uC, but i have never play with BT. Could you guys recommend me the SIMPLIEST BT example? I just want to send a byte and to read it in the nrf comm app or wherever.

Thanks a lot!
