Error: L6218E: Undefined symbol catch_rest (referred from app_task.o).

Hi Audi,

Thank you for posting your questions online.

Please check here(7827.ble_app_barebone.zip):

Quick way: rebuilt the project you will see the errors.

Thanks

Hi there, I solved this issue of mine. I think it was due to some SDK files being edited by mistake that kept bringing up this error. Once I changed it back to the original files it went away.

But now I have an issue where it seems the code doesnt actually work. I am not sure where I am going wrong. Could you comment on why it may not be working for me?

I even tried to put in arch_printf() to see where it seems to stop but nothing shows up even though I have a test to see if the suer_scan_start() function ever executes and LED does turn no but no print debug.

Is there a way to improve or change my code so it works?

Hi Audi,

Could you please provide some infos:

1, Which SDK you are using.

2, which example you are using.

3, Briefly having a description on your goal.

It seems you want scan for devices under advertising?

If so, it is impossible, BLE can't work as both central and peripheral. You need change the role when you needed.

reference: BLE_SDK6_examples/connectivity/multirole at main · dialog-semiconductor/BLE_SDK6_examples · GitHub

If not, please give us more descriptions 

Thanks

JH_Renesas

Hi, 

Thank you for pointing that out to me.

1. I am using the latest SDK which is 6.0.22.1401

2. I am using the ble_app_barebone example and I have included the files for it below.

3. What I am trying to do is the following:
I have a BLE beacon named dx54321 and what I want to do is that the Dev board will continuously scan for this beacon and determine its RSSI values. If lets say the beacons comes within 4m then it activates the LED (maybe another output in the future). Has soon as the beacon leaves the range then it deactivates the LED. There can be multiple beacons all advertising the same name and they all can trigger the dev board.

Please find my attached code (also I changed the GAPM_SCAN_ACTIVE to GAPM_SCAN_PASSIVE)

ble_app_barebone (3).zip

So, you need set DA14531MOD as a central. but barebone is a peripheral example.

The following examples are recommended for your application. More in our github.

BLE_SDK6_examples/connectivity/active_scanner at main · dialog-semiconductor/BLE_SDK6_examples · GitHub

BLE_SDK6_examples/connectivity/central at main · dialog-semiconductor/BLE_SDK6_examples · GitHub

Thanks

JH_Renesas

Thanks for the reply!

I am curious as to why you are recommending the central mode? Would it not be better for my system to run in observer mode and just read the advertising packets?

I am pretty sure advertising packets would contrain the RSSI values or am I misunderstanding it and need to connect to it to read the rssi values?

Also when I try to build the central project after linking it following the instructions i get the following error message:

Not sure what to do, since nothing was changed.

Hi Audi,

1, Only central mode can scan, only peripheral mode can advertise. You must switch the mode in your software.

2, From the screenshots you have shared, is that you are trying to debug the project directly from the BLE-SDK examples folder of the GitRepo.
You should copy/paste the example you are interested in inside your SDK with the rest of the SDK examples included.
Then use the python script included to fix the paths to your SDK. 
The rest of the settings seems OK to me. 
Keil is trying to locate the jlink_DA14531.ini which is part of the SDK folders and not from the GitRepo folder. This is why you cannot debug.

BR,

JH_Renesas 

Hi JH,

Thanks for your reply but I have done exactly what you said and even redirected the initialization file to jlink_DA14531.ini  and still get the same error. 

I even redownloaded the SDK and examples but same error persists. It just won't build.

The Zip file of the project is attached for your reference.

Hi Audi,

please double click sdk_arch and add the library file from the following path.
