Hi,
I'm using a QCA9377-3 chip (SDIO+UART) and am struggling with getting proper BT5.0 support in Android.
Software setup:
- Android 11 (AOSP tag android-11.0.0_r36)
- Android standard Bluetooth stack (fluoride)
- qcom firmware: qca9377-lea-3-0_qca_oem r3000037.10
The initialization of the BT chip goes well, download of both fw and nv files is successful.
Then the stack talks to the chip to discover its features/capabilities and that's where it goes bad:
- The firmware doesn't seem to reply properly to the HCI_BLE_READ_MAXIMUM_DATA_LENGTH command.
When issuing that command, the fw respsonse is missing the 8 bytes (4 * uint16_t) values so the stack crashes - The firmware also seems to report a wrong HCI_BLE_READ_DEFAULT_DATA_LENGTH as well (0)
Are those HCI commands supposed to be supported by the r3000037.10 BT firmware?
Regards,
Gary
