I try to establish a connection from nRFConnect Desktop using nRF52840DK to some hearing aid peripheral, but connection is immediately dropped after sending the first command. Also using some adjusted examples from nRFSDK in central role, will lead to same situation, where peripheral just disconnects.
It will work from nRFConnect Mobile on Android 11 and 9. There it connects successfully, and can read out all services and characteristics. It is also possible to connect/pair to the peripheral from Windows 10.
Find attached the logs from nRFConnect Desktop and Mobile and some wireshark logs for nRF5280 (failed) and Android/Win(worked)
Tested with nRF52840DK and also nRF52840Dongle. Same result for both.
Also tried to use some other BLE stack and adjusted different connection parameters like Window Offset, Interval, Timeout, CSA#2, PHY...with no success.
Regards
Heiko
