I'm working with a ble open source. Here i attached the captured abnormal case of the connection update Request PDU from the slave. Please refer to the attached picture. The slave shall not send the connection update request control PDU to master as i know.

Please feel free to tell me what you think about the abnormal case?

Hi,

In the direction field you can see that the packet is sent from the master to the slave...( M -> S)

I'm using a nrf52 DK in the central role and a arduino uno in the slave role with an BLE open-source from the github which means the nRF52 Dk does not make any problem. And the direction of the connection update req is the salve to the central when checking the direction with Ellisys BLE analyzer. I think that the BLE open-source that i'm using has a bug on this issue.
