It appears you’re encountering difficulties connecting your Amazon V-peak Obdii Bluetooth adapter to your iOS device, such as an iPhone or iPad. This is a common issue for users attempting to use Bluetooth OBD-II scanners with Apple products, and we’re here to clarify why this happens.
The Amazon V-Peak OBDII adapter, like many similar ELM327-based devices, is designed to wirelessly transmit diagnostic information from your vehicle’s OBD2 port. This data can then be accessed and interpreted by compatible applications on your smartphone, tablet, or computer, providing valuable insights into your car’s engine and overall health. These adapters are incredibly useful for both car enthusiasts and professional mechanics for tasks ranging from reading fault codes to monitoring real-time engine performance.
The core of the problem lies in the Bluetooth protocol compatibility between the Amazon V-Peak OBDII adapter and iOS devices. While Android devices generally pair seamlessly with standard Bluetooth devices through the device’s Bluetooth settings, iOS devices like iPhones and iPads often require Bluetooth devices to adhere to specific Apple protocols for pairing in this manner. In the case of many ELM327 Bluetooth OBDII adapters, including the Amazon V-Peak model, they are not designed to pair directly through the iOS Bluetooth settings menu.
As you’ve rightly observed, while your Android device readily discovers and pairs with the ELM327 adapter, your iPhone or iPad fails to even detect it in the Bluetooth settings. This is not necessarily an indication of a faulty adapter but rather a limitation in how iOS handles Bluetooth connections for certain types of devices.
The On-Board Diagnostics II (OBD-II) protocol itself is universally adopted by virtually all modern vehicle manufacturers. This standardized system allows for a wealth of diagnostic information to be accessed, regardless of vehicle brand. You can delve deeper into the specifics of the OBD-II protocol and its evolution on platforms like Wikipedia:

However, the issue isn’t with the OBD-II protocol itself, but rather with the Bluetooth connectivity method employed by the Amazon V-Peak and similar adapters when interacting with the iOS ecosystem.
The reason for this incompatibility often boils down to the type of Bluetooth profiles supported and how iOS applications are designed to communicate with external hardware. Many apps designed for OBD-II diagnostics on iOS expect to connect to adapters via Wi-Fi instead of Bluetooth, or they are specifically developed to work with Bluetooth Low Energy (BLE) OBD-II adapters, which are designed to be compatible with iOS devices.
In conclusion, while the Amazon V-Peak OBDII Bluetooth adapter is a functional and popular choice for OBD-II diagnostics, its Bluetooth implementation is generally not compatible with direct pairing to iOS devices through the standard Bluetooth settings. This is a characteristic of many ELM327 Bluetooth adapters and is not unique to the Amazon V-Peak. For iOS users, exploring Wi-Fi enabled OBD-II adapters or Bluetooth Low Energy (BLE) OBD-II scanners might be necessary to achieve seamless connectivity with their iPhones and iPads.
