[RaviPaswan]

I am currently learning nRF52840 , I started the BLE fundamentals course , and this the lesson 1 exercise , It Worked Fine , after the lesson 1 , none of the lesson's exercises Solution in working , There is no error while building and Flashing , still the DK doesn't show any effect even the led1 isn't blinking

Hi Ravi,

Could you check whether your DK is working well? Is this a new DK or have you used it before?

Do you have any peripherals attached or have done any hardware changes to the DK?

Regards,

Priyanka

yes i am sure the DK is working well, because I can Run Other programs fine, But while Uploading the BLE fundaments course of lesson 2 -4 , the VS code says Bulid Successful and Flash Successful , but the DK doesn't work

All the Excercise of nRF SDK fundamental Course and The Exercise of BLE course Lesson 1 are working perfectly file , But the excercises of Lesson 2 - 6 of BLE courses are not working , although there is no error in the code and while programming also there is no error , but the I can't Discover/Connect in the NrF mobile application

Hi,

I understand that, but could you try to build a sample application (not from the fundamental lesson preferably), like the hello_world or peripheral_lbs for instance and see if this works?

Thar's okay, but it would be great if you could attach the build logs that occur when you build.

Could you also mention your OS and whether you use an Android or iOS mobile phone?

This is Build Log : Build Log

Yes the sample programs are working fine 

Also when I am using the keil studio Beacon Example, My Mobile Device  can discover nRF board and Everything is fine

This page shows "This page does not exist". Not sure why and I am not able to view anything.

I tried few samples and unfortunately I am not able to replicate your issue. Could you tell me which SDK version you tried with? I tried with the v2.6.1 and everything was working well. 
Which is your phone? are you working on Android or iOS? 

It does seem strange that your LED1 is not blinking with the lesson 2 exercise 1
