Hi @ysong,

Please note that if the length of packet is a bit long, you also need to adjust baud rate to 230400 or higher.

how can we set baud rate higher than 230400?
since the available options are
{ "paramId": 2, "category": "General","paramType": "select", "type": "int64", "name": "Baud Rate", "argument": "baud_rate","value_range":[-1,1], "value_accuracy":6, "options": [115200, 57600, 230400, 38400] },
