Testing
Commission BL602DK and after connect to Wi-Fi router. Changing IPv6 address prefix of Wi-Fi router four times will get BL602 crashed.
With this PR, changing IPv6 address prefix of Wi-Fi router four more times will not get BL602 crashed.
The uartRead function returning 0 results in Status::FailedPrecondition, which causes an unexpected exit of the RPC and leads to a crash.
uartRead begins to retrieve the last byte from the data queue while a UART FIFO RX timeout interrupt occurs. At that point, the last byte has not yet been read, but it signals to the RPC task that data is available. The last byte is then read by uartRead, and when uartRead is called again by the RPC task, it returns 0.
The fault occurs in extreme environments and during stress testing. We have conducted tests using the Matter auto-test framework, which employs the PRC protocol to communicate with the device for Matter testing. After dozens of tests, we observe this fault occurring once.
