I am working on a Bluetooth Low Energy (BLE) project using the nRF52840 Development Kit (DK), which has been reconfigured to simulate an nRF52805 chip. The firmware is based on Nordic Semiconductor’s ble_app_hids_keyboard example, with modifications to implement a BLE HID Gamepad. I am using the S113 SoftDevice and have successfully tested the functionality with Android devices. The gamepad is recognized as a HID device, and it works as expected on Android, verified using the hardwareTester website.
