Currently only supports 9600bps communication is not supported AT instruction. Passthrough when communicating hostsfrom the machinemust have a certain amount of time interval between packets. For examplethe packet length is 500 bytes and packets sent between time interval can be set to not less than 600ms. Otherwisedata may be lost.
