SRWF-1100A module is used to supply enable design for customers, the module does not take with MCU by itself , it only offer customers user interface for operation. Condition: Power Supply Work voltage of module is 1.8V-3.6V, recommending to use 2.8V. If the working voltage of MCU is higher than module`s, between each working port and MCU I/O port must be linked with resistance in series to separate them, and the range of supplying voltage between them is not too far. (recommending the same power supply to offer electricity) RE/TE Control instruction: RE/TE is used to control power of data receiving in expansion and transmission

Question about scatternet

Sun, 20 May 2007 08:42:33 -0600

Hi, Im working with Bluetooth, more precisely, with scatternet type ( one master and more than one slave). When a master is transmitting/sending information to a particular slave, the master must leave the connection openned with the other slaves, or it must close the connection? Or put them in spark/low mode or else? I had been searching in Internet and documentation an answer to my problem, but there is nothing. I need this question because I have to write C code for an aplication of bluetooth. Could you help me or give the URL to HOWTOSa/tutorial...??
