... At this point the connection is established and GPIO1 (indicating the connection status) on both Client and Server boards becomes high. On the GS-BT2416C1DBAT1 board an LED is connected to GPIO1 and therefore the connection is also shown by an LED which is on. GPIO3 on the client board must now be put at HIGH level allowing the client to send and receive DATA from the server ...

... Each module has its own address which identifies the module itself in the network. The above examples were used with addresses 0080E1000001 and 0080E1000002. Modules on the GS-BT2416C1DBAT1 board may have different addresses. Before starting to send commands, the module address can be found with the command AT+BTSETTINGS=? which shows the relevant information of the module including the BT address ...
