GSBT2416C2DB.xxx 7 - AT COMMANDS APPENDIX This section is applicable to demoboard with AT command FW downloaded ( GSBT2416C2DB.AT1 ) Purpose of this section is to describe all the necessary steps to establish a connection between two Bluetooth GS-BT2416C2DB.AT1 demo boards in a Serial line /Cable replacement application. ( This connection example is also reported on OBSTFW-101 datasheet, Application Notes (vers 1.6)) SETUP & CONNECT To perform the connection you need two PC and two GS-BT2416C2DB.AT1 boards.

GSBT2416C2DB.xxx MACRO INSTRUCTIONS With the version 1.2.1.8 of OBSTFW -101 has been introduced the MACRO concept with the commands AT+BTMACROSTART , AT+BTMACROSTOP and AT+MACROCLEAR. These commands work in such a way that all the commands written between AT+BTMACROSTART and AT+BTMACROSTOP commands will be stored inside the internal flash memory and executed at each power up of the module.

GSBT2416C2DB.xxx POINT to POINT CONNECTION Modules with AT commands firmware can only perform point to point connection which means only a connection per time can be activated. A module can be connected with several other modules but it has to disconnect the previous connection before to activate a new one. Suppose to have a Client C1 which need to connect with Server S1,S2,..
