NRF51422 Bluetooth: Long time between send and receive from message

Fabrice

Hello together,

I' am working on a Bluetooth application and have a problem with the transmitting time of the Bluetooth.

In this Screenshot you can see the end of my command which i want to send from my NRF422 to my NRF422 Dongle. The second peak from the Debug pin indicates the send of the "Request Transfer" for the Bluetooth message. The Buffering just takes 0.26ms.

In this image I receive and Send my Bluetooth message via UART. (second peak debug pin). The message i received is exactly the same i sent and it is working every time. The Time for the Buffering is just 0.41ms.

Now my Problem: The Time in between send and receive is about 160ms and that's to long. Does someboy has experience with the Bluetooth Stack and knows what could cause the problem?

Thank you.

Best regards,

Fabrice
