#BL602 #SPI ... Now writing about the 4 fixes I made ... 1️⃣ SPI Data Pins are flipped 2️⃣ SPI Phase should be 1 (though it behaves like 0) 3️⃣ Doing SPI Chip Select ourselves 4️⃣ Pin 0 switches on WiFi LED. Thanks for bearing with this long thread on #PineCone @PINE64 🙏

#PineCone #BL602 @PINE64 with Acupuncture ... Erm Logic Analyser

#PineCone #BL602 @ThePine64 tested OK with #BME280 over #SPI ... Here's the wiring that doesn't light up the WiFi LED 💡

#BL602 #SPI Phase 1 ... Looks suspiciously like Phase 0 🤔

#PineCone #BL602 SPI works OK yay @PINE64 ! Had to change SPI Phase from 0 to 1 ... Which doesn't sound logical 🤔

Getting desperate with #BL602 SPI ... Let's try to dump all BME280 Registers ... And see what works
