Communication uses sockets with standard Data frames and the above Action frames. Switch consoles presumably only use the Action frames to communicate with each other?

The key derived by ldn-sysmodule is used directly as the static CCMP key for all data-frames (CCMP / MIC is standard).
The key derived by ldn-sysmodule is used directly as the static CCMP key for all data-frames (CCMP / MIC is standard). However, with [[#GroupInfo]]+0x8A value 3, standard WPA2-PSK is used instead.
This uses infrastructure-mode (AccessPoint), and DHCP is used. The group-owner is the AccessPoint. Note that the probe response includes the same Nintendo tags included with the beacon. Once connected, the group-owner sends the same Epigram-vendor Action frame(s) described in [[#ldn]]. At this point socket communication can begin, including DHCP usage.

The DHCP server thread is started by the "nn.lp2p.StateMachine" thread eventually during group [[#CreateGroup|creation]]. The DHCP Offer option values are the following, at least when connecting with encryption disabled from a Linux machine:

The SSID in the beacon is hidden (all-zero with the same length as the original SSID). The beacon contains two custom Nintendo tags with OUI <code>00:22:aa</code>. The beacon is identical to ldn, except for the following (besides SSID length difference and the lp2p-only Nintendo tags):
The SSID in the beacon can optionally be [[#GroupInfo|hidden]] (all-zero with the same length as the original SSID). The beacon contains two custom Nintendo tags with OUI <code>00:22:aa</code>. These Nintendo tags are not used when standard WPA2-PSK is being used. The beacon is identical to ldn, except for the following (besides SSID length difference and the lp2p-only Nintendo tags):
* "Tag: Traffic Indication Map (TIM)": "DTIM count" for lp2p is 1, with ldn it's 0.
* "Tag: Traffic Indication Map (TIM)": "DTIM count" for lp2p is 1, with ldn it's 0.
* "Tag: HT Capabilities (802.11n D1.10)": "HT Short GI for 20MHz" is set to "Not supported", for ldn it's "Supported".
* "Tag: HT Capabilities (802.11n D1.10)": "HT Short GI for 20MHz" is set to "Not supported", for ldn it's "Supported".
