Is there a Completed Code BLE Characteristics, from the beginner's tutorial ported for SDK version 12.3?

[fernandolns]

Hi,

I'm a beginner of BLE and I did everything from the three BLE tutorials, that uses sdk 11. However when I try to do it in sdk 12.3 it doesn't work, because there are some changes from one version to another.

Where can I find the completed source code for the BLE Characteristics, a beginner's tutorial for sdk 12.3? What kind of modifications are needed in order to work properly? I've seen that it needs sdk_config.h and that there are some changes in these: "device_manager.h","pstorage.h", "app_trace.h" to these: "peer_manager.h", "fds.h", "nrf_log.h"

Did anyone manage to make BLE Characteristics work in sdk 12.3?

Here is the main.c, where I was getting the error "L6218E: Undefined symbol app_uart_init (referred from main.o)", then I commented uart_config and the error disappeared, hence it compiled and the BLE doesn't work though.

This is the other main.c, in this one I started by using the ble_app_template, then implementing what was in BLE Characteristics, like the temperature part and adding some lines. Others configurations of BLE already came implemented in the example. However in this one there's no uart_config,then it compiled with no errors and it doens't work either.

In both of them the led 1 is supposed to blink when there's bluetooth advertising, which didn't happen. I think there's something to do with uart_config, but I might be wrong.

Any help would be very much appreciated.

Thanks in advance

Hi fernandolns!
There is not much difference between SDK11 and SDK12, and you should be able to follow the tutorials for SDK11 without too much trouble. Do you only have trouble with the BLE Characteristic tutorial?

Hi Joakim, I see, yes, I've been trying to adapt especially the BLE Characteristics, furthermore I followed those three beginners tutorials and the one to migrate device manager to peer manager. However I'm getting an error of undefined symbol at app_uart_init, and sdk_config.h was adapted from here, but it still persists, I think I might be missing something, I'll keep trying, thanks!

I would use the ble_app_template example from SDK 12, where the peer manager and the sdk_config.h file is already implementet. You should be able to follow the tutorial using that example. I did it myself a while ago, but I don't have the finished code I'm afraid. Let me know if you face any problems.

Hi! I did as you said and followed the tutorials. I kept the sdk_config.h from ble_app_template, in fact I copied the main.c, our_service.c and our_service.h from BLE Characteristics completed to the folder of the template, overwriting the main.c there. then I did the tutorial to migrate to peer manager. However I get this error "L6218E: Undefined symbol app_uart_init (referred from main.o)". I have no clue of what can be wrong.

I would say the easiest move would have been to use the template example in SDK 12.3 and just follow the tutorial. I don't know why you are trying to initialize the uart? I can't find any reference to the app_uart_init() in the main.c from the Characteristic tutorial. Maybe you could upload your code?
