nrf radio ble timing

SYSTEM ONLINE

Radio Time Calculator (BLE On-Air Timing)

Calculate the exact physical occupation time in the 2.4 GHz band by the nRF radio chip (Radio Peripheral). The tool takes into account the physical BLE frame format for various modulations (PHY) including 1 Mbps, 2 Mbps and Coded PHY (Long Range). Knowing the transmission microseconds is crucial for battery calculations.

Radio Link Parameters

Without Data Length Extension (DLE) max 27. With DLE max 251.

Physical BLE frame format

Preamble: 1 B
Access Address: 4 B
PDU Header: 2 B
Payload: 20 B
CRC: 3 B
Total frame size: 30 B
On-Air TX Time
240 µs
The radio will draw approx. 5-7 mA of current (depending on power) for exactly this fraction of time.
