Connecting External Bluetooth module to iMX Running Android

jagadeeshmarada — Tue, 22 Jan 2019 11:38:49 GMT

I am having sim800c module from simcom which is having both GSM+bluetooth with it.

how can i used it as a bluetooth adapter connected to my iMX6 q7 Development Board,

i have done the fallowing changes in my android AOSP

#Enable Bluetooth in init.rc file

# Prepare for bluetooth
    chmod 665 /sys/class/rfkill/rfkill0/state
    chown bluetooth net_bt_stack /sys/class/rfkill/rfkill0/state
    write /sys/class/rfkill/rfkill0/state 0

in BoardConfig.mk file, support is given for Broadcom and qcom modules

which are present in Hardware/Broadcom, hardware/qcom

how to add vendor specific HAL implementation for simcom800c to work with imx6 q7 board?

will broadcom HAL acts as generic for simcom also?

# However i have enabled broadcom as true for testing purpose

BoardConfig.mk

# Broadcom BCM4339 BT
BOARD_HAVE_BLUETOOTH_BCM := true
BOARD_BLUETOOTH_BDROID_BUILDCFG_INCLUDE_DIR := device/fsl/imx6q/bluetooth

after successful build here are my logcat prints
