This pattern represents an average deviation in payload. 140 155 175 kHz 10101010 sequence in payloadb b. Pattern represents the maximum deviation in payload for 99.9% of all frequency deviations. 115 140 – kHz Channel spacing – 1 – MHz Table 36: BLE RF Specifications Parameter Conditions Minimum Typical Maximum Unit Frequency range – 2402 – 2480 MHz RX sensea a. Dirty TX is On. GFSK, 0.1% BER, 1 Mbps – –95.5 – dBm TX powerb b. BLE TX power can be increased to compensate for front-end losses such as BPF, diplexer, switch, etc.). The output is capped at 12 dBm out. The BLE TX power at the antenna port cannot exceed the 10 dBm specification limit. – – 8.5 – dBm Mod Char: delta F1 average – 225 255 275 kHz Mod Char: delta F2 max.c c.
