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..

The open alternatives for the Nordic NRF5x are not at the same quality level as the Softdevice:

- the idle power consumption is noticeably higher, there are open bugs for more than 1 year about that

- They are not validated by the Bluetooth consortium. You're gonna need to get your own certification to claim product supports BLE.

If you're building a commercial BLE product - my advice: go with Softdevice.
