Over the weekend I took a side trip with my AVC processor to include a wireless BlueTooth transceiver. This will allow me to communicate with the robot as I run various experiments. It turned out to be fairly easy.I have used the RN-42 in the past on other work projects. These look to the embedded and the host (PC) side just like a serial port. You do need to configure the RN-42 and the host to get various parameters configured properly. These mostly consist of the baud rate, PIN, and host name.<\/p>\n
Out of the box the RN-42 is configured for 115200 baud. This was an issue as my current test bed Arduino can’t deal with such a high baud rate using the SoftwareSerial bit-bang library. So I sloowed it down to 9600 for right now with the intent to crank it up to the fastest that can be handled by the system.<\/p>\n
During this adventure, suddenly the magnetomer started to saturate and display 4096. I could get it to work again by lowering the gain but at a lack of sensitivity. And then a day later, the original sensitive gain worked fine. I wonder what happened there? Some device with a magnetic field turned on? Perhaps the ballast on my articulated florecent magnifier lamp?\u00a0 Who knows.<\/p>\n","protected":false},"excerpt":{"rendered":"
