Flash adapter connectivity
The OBD flash adapter uses BLE (Bluetooth Low Energy) to communicate with your phone, acting as a secure pass-through between your car’s ECU and CAN-Bus system and the flashing protocols running on our servers.
Tip: For the most reliable flashing experience, use a device that supports BLE well, keep the phone close to the adapter during flashing, and avoid battery saver modes that can restrict Bluetooth in the background.
