I apologize up front for the length of this post, but I want to provide as much info as I can. I have a Solar Powered Air Quality Sensor kit that I purchased as a Kickstarter. Shortly after I got it, I received a message from Cindy in customer service that they may have sent the wrong Grove MiniPro Plus board with my kit, and sure enough, they did. I chose to reprogram it myself instead of sending it back for exchange. Well, I thought I would try connecting the HM3301 directly to my Raspberry Pi to see how that would work. After purchasing a Pi2Grover and some extra Grove cables I hooked it all up. I did install the bit-banger Grove driver that was suggested to get the HM3301 to talk to the Raspberry Pi. After fussing with it a while, trying different ports and such, I had no luck getting data - the driver would return a time-out error of some sort. I gave up on that path, but it was awhile before I got around to it again. I downloaded the latest Air Quality Sensor software to the MiniPro Plus and assembled the kit as per instructions. I fired it up and could see the LEDs blinking on the boards like they should, but I never got any AQI reports running the weather sense monitoring software. I tried reconnecting everything and adjusting the pins on the antenna board, but still nothing. Any suggestions on where to go from here?
