Response from the customer support:
lets seeHi XXX,
Thank you for your question.
You are correct that the original ELM Electronics company never officially released a “v1.5” version of the ELM327 chip. The “ELM327 v1.5” wording is commonly used in the aftermarket OBD industry to describe compatible firmware based on the older and more stable command set between v1.3 and v1.4b.
In practice, “v1.5” is mainly used to distinguish these adapters from many low-cost “v2.1” clones, which often have reduced command support and poorer compatibility. In addition, many OBD apps themselves specifically recommend or require a “v1.5” adapter for best compatibility, so manufacturers commonly use this wording to match those app requirements and user expectations.
The important point is compatibility and stability:
Supports all standard OBD-II protocols
Works with popular apps such as Car Scanner, OBD Fusion, Torque, etc.
Provides stable BLE communication for iOS and Android devices
Please let us know if you have any additional questions.
Best regards,
Veepeak Support
I will get both of them tomorrow
