Question
The BLE composite HID device failed to enumerate！
Hello,
Recently, I have been working with the SensorTile module (STEVAL-STLCS01V1) featuring the STM32L476JG and BlueNRG-MS. I successfully created standalone HID devices for both keyboard and mouse. However, when I attempted to implement a composite HID device, the computer failed to recognize it properly.
I would like to know if BLE supports HID composite devices.
Could you provide some guidance or suggest possible solutions? Thank you!
I will paste my hid_report_map below.
