I have merged the ajtcl in my FW project running on my board. There is no WiFi function on my board , so I bought a GT202 to use the WiFi function mentioned in https://allseenalliance.org/developers/develop/tutorial/arduino-and-gt202 But I can't find any document or spec about how to control GT202 with SPI interface. It would be very helpful if anyone can provide the spec or samples about how to control GT202 with SPI interface. Thanks!!
