Docs on S110 software events?

[Mike Wirth]

Folks,

Is there a document that describes the events generated by the S110 Soft Device and their interpretation? (Note: they're not listed in the S110 SoftDevice Spec v1.1 PDF doc, and I can't find them in the (Doxygen-generated) API webpages included in the API release :-)

In particular, I infer from the spec that there are ACTIVE and nACTIVE events to signal when the radio is (about) to be powered on and off. Very useful. But I also need an event when the radio switches from transmit to receive or vice-versa (to control some external circuitry). Is that available? (short of monitoring supply current :-)

Be aware that if you try to control an external PA (which it sounds like), you can use VDD_PA physical line for this instead of a software solution. That line will be high while the radio is actually transmitting, and can therefore be used as a control signal directly (or through some sort of buffer).

We normally don't recommend using an external LNA, since all practical experience shows that this doesn't give (almost) no extra range. The reason seems to be that it will amplify noise as much as it amplifies the signal, and hence gives (again, almost) equal SNR, which is what actually matters. Additionally, the increased noise gives poor blocking, and hence hurts the co-existence performance.
