CC2642R: BLE disconnecting continously

BIPIN CHAVAN

Part Number: CC2642R

Hi all,

I am doing some developing on cc2642 using cc2652launchpad and SDK version "5.10".I have few questions related to it.

1)Do I need to import ble stack explicitly or it is used as library in example projects like (simple peripheral/simple peripheral OAD onchip) because i dont see any workspace related to ble stack in examples.

2)while using Simple peripheral OAD onchip example what are other dependency projects?(according to my knowledge BIM,Persistent are the only dependencies.)

3)what are the exact steps to execute Simple peripheral OAD onchip example?(what i am doing is first i am flashing the Persistent, application and BIM hex together using flash programmer in given sequence and then flashing oad.bin file. After doing this,ble device is discoverable but when i connect to the ble, immediately it gets disconnected(need guidance on this).

second method is i am creating super hex out of two hex(BIM and PERSISTENT) and oad.bin and flashing that hex on device still getting same mentioned issue.

Can someone please guide me on how to exactly perform the OAD using Simple peripheral OAD onchip example? am i using correct method to create final image?

Is there any other configurations to be done on BLE?

Following are the projects i am currently using. Guidance on my issues will be appreciated.

Thanks

Hi,

You seems to be using the OAD examples. Please make sure to follow the steps detailed in our documentation and SimpleLink Academy.

Thanks for the response.

i have followed the steps in document. Bootloader is working fine and it is jumping to main application. Now the problem is device is advertising with name "SP oad-onchip" but when i try to connect to the device ,it gets connected and immediately gets disconnected due to which i am not able to perform OAR reset from the app and to push the device in persistent mode so that OAD can be started. Any guidance on this will be helpful.

Thanks

Hi,

Could you specify what do you use as central device? (mobile phone, simple_central example, BTool) Have you considered using a different central device to be sure the issue is not coming from it? You could also see if you can get an error code from the central device that will help to identify the issue.

Could you please share the UART log outputted by the device?
