Table 4. Electrical Characteristics
Notes:
1.
Table 5. Radio Characteristics
Table 6. Range Characteristics (Approximate Range In Office Environment)
The readings shown in Table 6 are approximate and may vary depending upon the RF environment. Bluetooth hops in a
pseudo-random fashion over the 79 frequencies in the ISM band to adapt to the interference. Data throughput and range
vary depending on the RF interference environment.
Figure 2 shows the module’s pinout and Table 7 describes the pins.

If, in slave mode, there are bursts of radio ON time that vary with the windows. Depending on how you set the windows, that
determines your average current.
