nrf51DK data tranfer issue

[pavan]

Hello All,

I am working on nrf51dk , we are facing the issue if we send > 8 bytes of data in one time from Uart console then BLE_NUS will reset..

Our Setup: ECU --> K-Line Trans receiver --> Android App

The feature of K-Line is that what ever we transmit will be sent back to the BLE.. When we send bytes of data from Android App then same data will be received back to the Android App.. If we are sending < 8 bytes of data then there is no issue but when we send >8 bytes of data then BLE_NUS will reset..

Kindly refer to the below link for more information.. we didn't understood the solution described for the below query. Kindly provide sample code how to rectify the issue...

A nRF51 rarely resets without a reason. Have you tried debugging? Most likely one of your function calls returns an error and by default this causes the system to reset. You can however, debug like this to find the error code and origin. If you find an error, look up the code in the documentation of the guilty function to get a clue about what is going on.

Hello,

But my question is why BLE_NUS will reset after sending more than 8 byes?

[MartinBL]

I don't know. As mentioned above you will have to debug and give me more information. It might also help if you upload your code.
