This section gives an overview of the power profile of the central connection event implemented in the SoftDevice.
Figure 1. Central connection event
| Stage | Description | Current Calculation1 |
|---|---|---|
| (A) | Pre-processing | ION + IRTC + IX32k + ICPU,Flash |
| (B) | Standby + XO ramp | ION + IRTC + IX32k + ISTART,X16M |
| (C) | Standby | ION + IRTC + IX32k + IX16M |
| (D) | Radio start | ION + IRTC + IX32k + IX16M + ʃ(ISTART,TX) + ICPU,Flash |
| (E) | Radio TX | ION + IRTC + IX32k + IX16M + ITX,0dBM |
| (F) | Radio turn-around | ION + IRTC + IX32k + IX16M + ʃ(ISTART,RX) + ICPU,Flash |
| (G) | Radio RX | ION + IRTC + IX32k + IX16M + IRX |
| (H) | Post-processing | ION + IRTC + IX32k + ICPU,Flash |
| (I) | Idle - connected | ION + IRTC + IX32k |
Important: When using the 32.768 kHz RC oscillator, IRC32k must be
used instead of IX32k.
