BT calling version for 1gb/16gb HEHUI model ONLY !!
Latest version - BUT - this is not officially released by IQI
This means that you may need to go back to the last non BT dialler version to get OTA’s
This was made specifically for us at my request - so it’s your choice if you want to use it.
You HAVE to use Firmware Upgrade option in SP Tools !!
Use SP Tools version SP_Flash_Tool_v5.1712_Win from the web.
Version - AQR-LAUNCH-I4P-1601-Fitness-HEHUI-BT-NHT-V01-20171121
