Here's the Decompiled #BL602 #WiFi Supplicant that handles WiFi Authentication ... Decompiled code looks readable

#BL602 #WiFi Payload Handler calls rxu, txl and txu functions ... Fortunately these are defined in the AliOS / RivieraWaves Source Code we saw earlier

@jlamothe Yep it's good to learn Embedded Rust ... Applying it can be tricky though ... I'm fighting some Rust roadblocks on BL602 right now 🤔

txl_payload_handle handles #BL602 #WiFi Payloads by doing ... nothing! But txl_payload_handle_backup seems to be the right function that handles WiFi Payloads 🤔

Here are the #WiFi Event Handlers for #BL602 WiFi Kernel ... txl_payload_handle looks interesting ... Let's hunt for it

Back to ke_evt_schedule, the function in #BL602 #WiFi Driver Kernel that handles every WiFi Event ... Let's hunt for ke_evt_hdlr and discover the WiFi Events
