No. OBDAssistant operates in read-only mode. It passively reads data from your vehicle's diagnostic system — it cannot write to your ECU or modify any vehicle settings.
Only while using the app. Low-power BLE adapters like Vgate iCar Pro can safely be left plugged in without draining your battery. Higher-power Bluetooth Classic adapters should be unplugged when not in use.
WiFi OBD2 adapters take over your phone's WiFI connection, preventing internet access. Bluetooth adapters work simultaneously with WiFi, giving you full connectivity while diagnosing.
Currently Android only. iOS support is planned for a future release. Follow our updates for launch announcements.
