RE: vLinker MC+ BT+BLE does not wake up on next day

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. -

That’s more of a hardware behavior than a Car Scanner setting. Most OBD2 adapters wake when they detect ignition voltage changes or CAN bus activity, so if your car’s port stays powered even with the ignition off, the adapter may never “see” the wake trigger. You could try:
Checking your vLinker’s documentation or Vgate app for any sleep/wake settings.
Plugging it into a switched OBD2 extension so it gets power only with ignition.
Contacting Vgate support — they might have firmware tweaks for better BLE wake-up.
Unfortunately, BLE can reconnect easily when the device is awake, but it can’t remotely power up a sleeping adapter unless it’s designed to listen in sleep mode. -

I’ve experienced something similar with BLE adapters. Overnight sleep often breaks auto-wake, requiring unplugging. Maybe firmware update or Car Scanner setting tweak could help improve reconnection without manual intervention. -

I'm using a vLinker MC+ Bluetooth+BLE device together with Car Scanner (Pro) on my Android smartphone. The connection via BLE works fine in principle, where I selected the "vLinker MC-IOS" in the Car Scanner settings, since no specific ANDROID connection is shown (for BLE).
Having successfully started, I can have long and short rides, where the vLinker is automatically reconnected after a break of e.g. one hour for shopping etc. Data recording is continued then. That's fine so far. Only if I want to reconnect after a whole night, where the vLinker has fallen asleep in the meantime, I can't succeed to wake the vLinker up with my smartphone. So I always need to unplug the device and plug it in again, which is a little annoying with my car. After that the vLinker gets recognized and reconnected automatically - without any further steps necessary).
As far as I understood, device wake-up should be one of the favourite features of Bluetooth LE. Can anybody tell me what I might be doing wrong, do I e.g. have to change any of the default settings in the Car Scanner app?
Thanks for any idea which could help.

If the vLinker MC+ BT+BLE doesn't wake up the next day, it may be due to a power-saving mode, gbwhatsapp download battery depletion, or Bluetooth inactivity. Ensure it's properly connected, charged, and not set to deep sleep. Firmware issues or app settings could also prevent automatic reconnection or wake-up functionality. -

The only reliable fix is unplugging and replugging the adapter, or switching to the classic Bluetooth mode if your device supports it.
