Nutcracker Challenge: Blob-Free WiFi and BLE

I too am confused why BL602 and not ESP32?

Basically they want to reverse engineer this 10MB binary file:

components/bl602/bl602_wifi/lib/libbl602_wifi.a

Which references an internal closed-source sdk:

  phy_bl602.c
  phy_hal.c
  phy_tcal.c
  rfc_bl602.c
  bl602_rf_private.c
  etc..

So this is not actually kinda advertisement to raise aware-ness on the chip? I mean if the manufacturer is sponsoring this giveaway, why didn't they release the sources in the first place?

I would be very funny to discover they lose their source code :)

A more serious reason I could think of : maybe pine64 is trying to convince them to do just that, and this contest is to show them there is public interest (pure speculation from me, of course).

Pine64 and Bouffalo are two different entities. The former tries to ship open-source compatible hardware, the latter manufactures the chip.

So Pine64 is itself giving away 1000 pcs of the board? Assuming 5$ for each board, this challenge costs them 5k...
