How to solve the NCP error shown in the SDK log?

Last Updated on：2024-01-18 07:21:06

Problem description

ASH_FLAG TUYA check, abnormal_data_num:0.
ASH disconnected: EZSP_ASH_ERROR_XON_XOFF
NCP status: EZSP_NO_ERROR

Reason: The module is restarted.

Troubleshoot: If the CRC checksum fails more than three times, the NCP will be restarted. When the accumulation of an error reaches a threshold, the system considers that some issues on the NCP occur and will restart the NCP.

If you get EZSP_ASH_ERROR_XON_XOFF, it indicates there might be a problem with the flow control of the microcontroller.
