FSC-BT956B Datasheet Data is transferred between a Master and a Slave synchronously to SCL on the SDA line on a byte-by-byte basis. Each data byte is 8-bit long. There is one SCL clock pulse for each data bit with the MSB being transmitted first. An acknowledge bit follows each transferred byte. Each bit is sampled during the high period of SCL; therefore, the SDA line may be changed only during the low period of SCL and must be held stable during the high period of SCL.

FSC-BT956B Datasheet 8.2 Host PCB Land Pattern and Antenna Keep-out for FSC-BT956B Please check the picture below for Pad Structure and Keep Out Area: Figure 12: Host PCB-Top View 9. HARDWARE INTEGRATION SUGGESTIONS 9.1 Soldering Recommendations FSC-BT956B is compatible with industrial standard reflow profile for Pb-free solders. The reflow profile used is dependent on the thermal mass of the entire populated PCB, heat transfer efficiency of the oven and particular type of solder paste used.
FSC-BT956B Datasheet 9.2 Layout Guidelines(Internal Antenna) It is strongly recommended to use good layout practices to ensure proper operation of the module. Placing copper or any metal near antenna deteriorates its operation by having effect on the matching properties. Metal shield around the antenna will prevent the radiation and thus metal case should not be used with the module.
FSC-BT956B Datasheet As indicated in below, RF critical circuits of the module should be clearly separated from any digital circuits on the system board. All RF circuits in the module are close to the antenna port. The module, then, should be placed in this way that module digital part towards your digital section of the system PCB.
FSC-BT956B Datasheet Antenna Wrong Antenna Antenna PCB PCB PCB Better Best Figure 16: Recommended Trace Connects Antenna and the Module Routing of the RF-connection underneath the module should be avoided. The distance of the micro strip line to the ground plane on the bottom side of the receiver is very small and has huge tolerances. Therefore, the impedance of this part of the trace cannot be controlled. Use as many vias as possible to connect the ground planes. 10. 10.
