The three most significant factors are the voltage level at Vcc, UA RT baud rate and the operating mode. The hardware specification for the blu2i module allows for a voltage range of 3.
www.ezurio.com A slave on the other hand does NOT h ave prior knowledge of when a pack et will be recei ved and has to assume that a packet will be received from a master on every receive slot. This means that it has to leave its recei ving circuitry on for most of the receive slot duration.

www.ezurio.com AT&W AT+BTR<bdaddr_m> 9.5 Modem Control and Status Signals A serial port has DTR, DSR, RT S, CTS, DCD and RI c ontrol lines. RTS and CTS are locally controll ed to prevent local buffer overflow. The status of DTR, DRS , DCD and RI can be exchan ged with the remote peer device .
www.ezurio.com 10. Application Information 10.1 Antenna Position The antenna u sed on the BISM2 B luetoot h module is designed to be largel y immune from the effects of proximity detuning. Normally, antennas operating at 2.4GHz are affected by their surroun dings, so that great care is needed in their placeme nt and orientation.
www.ezurio.com 10.2 Power Supp ly Considerations The power supply for the Module has to be a single voltage source of Vcc within the ran ge of 3.6 V to 7.0 V. It must be able to provide sufficient current in a tran smit burst. This can rise to 65mA. The Module includes regulators to provid e local 3.
