You’re right; one of the cool features of Bluetooth Low Energy (BLE) is that it should allow devices to wake up without needing to be unplugged. Here are a few things you might want to try:

Dive into the Car Scanner app settings to see if there’s an option related to device sleep or wake-up behavior. Sometimes, apps have specific configurations for BLE devices that can help maintain connections more effectively. Ensure that both your vLinker device and the Car Scanner app are running the latest firmware and software versions. Manufacturers often release updates that can fix bugs or improve connectivity. Go into your Android phone’s Bluetooth settings and see if there are any power-saving modes that might be affecting the connection. Turning off any aggressive power-saving options could help. If none of these steps work, it might be worth reaching out to the support teams for either the vLinker or Car Scanner, as they may have specific fixes or insights into your issue.
