This post refutes the claim that researchers found a "backdoor" in ESP32 Bluetooth chips. What the researchers highlight (vendor-specific HCI commands to read & write controller memory) is a common design pattern found in other Bluetooth chips from other vendors as well, such as Broadcom, Cypress, and Texas Instruments. Vendor-specific commands in Bluetooth effectively constitute a "private API", and a company's choice to not publicly document their private API does not constitute a "backdoor".
The dude that wrote this blog is a goof…
Idiot thinks these are two different things…
Are they are trying to argue that malicious intent is needed to define it as a back door?
Moron…
A backdoor requires malicious intent, otherwise it’s just a vulnerability
