DA14531 BLE Detected issue

Hi PM_Dialog,

    In my custom board used DA14531 Module.

    Programmed DA14531 Module using  "codeless_531_set_two_standalone" which is available in DA145xx_CODELESS_6.380.12.6 .  

    Downloaded "Smart console"  app from play store.

   open the smart console app in android and the DA14531 Module detected in mobile.

   Here comes the main issue,

             1.In the app it detects the module but unable to connect module.(Its shown message like disconnected while trying to connect the module)

            2.But for another Module did the same procedure.It is detected in app and also connected.

 

Note:

1) Test conditions are same.

2) I observed the voltage levels are same for both the modules pins while connected and in the Smart Console app the device which is connected having strength of (-51db and above) and the modules which is showing disconnected in smart console app having (-48db) range .

    My doubt is is there any RF issue??

    or if anysome other issue let me know.

   Appreciate your help at the earliest.

 

Thanks and regards,

Pooja.

Hi pooja,

Hi pooja,

Thanks for your question online and for your interest in our TINY module BLE solution.

>>> 2.But for another Module did the same procedure.It is detected in app and also connected.

Are you using the same custom board?

In the custom board that you are unable to establish a connection, can you please try to replicate it with any of the SDK example? For instance, program the module with the ble_app_peripheral example of the SDK. Are you able to connect with a generic BLE Android application (for example BLE scanner) ?

Would it be possible to share a sniffer log, so that I can understand what is happening over the air?

When the connection fails, the module crashes, or advertising again? You could also the Power Profile of the Smart Snippets Toolbox to test it.

Since it is a custom board, did you follow the design guidelines as described on the DA14531 Module Datasheet?

Thanks, PM_Dialog
