🎀 Members 🎀

• mbox_msg — the message that BT sends over to WiFi. it's giving pen-pal energy fr fr 🫶
• msg_idx — the index of the message. yes, they numbered them, iconic behavior 👑
• bt_ci_compliance — an enum iwl_bt_ci_compliance. that's the type, that's the vibe ⭐
• primary_ch_lut — the LUT used for the primary channel, and it's an enum iwl_bt_coex_lut_type 🌸
• secondary_ch_lut — the LUT used for the secondary channel, also an enum iwl_bt_coex_lut_type. matching set, we love to see it 💜
• bt_activity_grading — the activity of BT, typed as enum iwl_bt_activity_grading 🔥
• ttc_status — is TTC enabled — one bit per PHY 🧚
• rrc_status — is RRC enabled — one bit per PHY 🦋

⚠️ heads up bestie: the following fields are only for version 5, and are reserved in version 4. so like, don't go reading them in v4 thinking you're gonna get real data, okay? 🙈

• wifi_loss_low_rssi — The predicted lost WiFi rate (% of air time that BT is utilizing) when the RSSI is low (<= -65 dBm) 😭
• wifi_loss_mid_high_rssi — The predicted lost WiFi rate (% of air time that BT is utilizing) when the RSSI is mid/high (>= -65 dBm) 💀
