Hi Karl

:Could you try to reinstall the Bluetooth Low Energy application in nRF Connect, and re-flash the nRF52840 DK that you are using on the central side, and see if this changes anything?

i did reinstall the app but no change i still get NRF ERROR BUSY

Thank you for confirming this.
Could you also re-flash the central nRF52840 DK device?
In this case we will need to look into why the central side is busy, and what else it might be doing.
In the log you provided earlier I am only able to see a sequence of READ_RSP and DISC_RSP events until it times out, but nothing about what the central is sending out.
Could you provide a sniffer trace of the communication with the device when this happens?

Best regards,
Karl

Thank you for providing both the video and the sniffer trace. I will have to discuss this with some colleagues. I will update you as soon as they get back to me.

Best regards,

Hello again, Ridhima

After having discussed this with some colleagues I think that the issue might be with the characteristic's configuration, since it seems that the read of the CCCD handle fails prior to the writing failing. The log also indicates that the read is unsuccessful and times out.
Could you share your characteristic's configuration?

Best regards,
Karl
