Thankfully #BL602 #WiFi Library libwifi was compiled with Assertions Enabled ... Makes Reverse Engineering simpler 👍

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

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
