beaconing example for nrf52840 stopped by vector

[Kalpesh Brahmbhatt]

Dear Sir,

I am using Example beaconing_nrf52840_xxAA_s140_6_1_0 in nrf5 SDK for Mesh_v3.0.0 get stopped after running for sort period. I have tried to debug but could not find any solution. I am using MINEW make MS88SF2 module. I am also attaching pictures for the problem. Kindly suggest remedial solution.

Hi, 

Are you using unmodified version of the example? Could you try to add the define DEBUG in your Preprocessor(Project -> Edit Options -> Preprocessor -> Preprocessor Definitions), then add a breakpoint on app_error_fault_handler() to see which error you get. You will see which error you get and which function is returning this error.

Hi,

Have you included all the necessary code files for the UART module and paths to the corresponding SES project file? Have a look at this.

Do the function return any error codes?

[Kalpesh Brahmbhatt]

Thanks again I have added all required code files and uart module and program. More over there is also same problem with original beaconning example in nrf5 SDK for Mesh from v2.0.1 to v3.2.0. Program run for some time and get halted on nrf52840 but original program run without any problem on nrf52832. But if I add uart routine on beaconning example for nrf52832 and check on RTT Viewer after running program APP_UART_COMMUNICATION_ERROR is observed immediately after power on.

Is that a Framing error?

(some of) the Nordic examples treat such things as fatal:
