Host records from the machine address every seconds bright 100ms;
Host records from the machine address every seconds bright 900ms;

KEY : Input pin internal dropdown. This pin high the from address to host clear have been recorded.
PIO : Extended functionality for setting module master/slave mode the default internal pull-up resistors from machine under the external pull-up resistor 1K To ground as the host.
Currently only supports 9600bps communication is not supported AT instruction. Passthrough when communicating hosts from the machine must have a certain amount of time interval between packets. For example the packet length is 500 bytes and packets sent between time interval can be set to not less than 600ms. Otherwise data may be lost.
