The telemetry data subscription uses serial communication. If the process is correct, please check whether the serial communication is stable.

It has been found that this exception occurs occasionally on some STM32 platforms, and this problem exists when using the wireless serial port module on the Linux platform.

Please try to increase the delay time before getvalue, and to solve the problem, It is needed to ensure that the serial communication is stable and does not lose packets.
