I also had to use an earlier Arduino version last week uploading code--I think I ended up using 1.5.4, arbitrarily. The problem was the compiler not finding the library (despite the application recognizing it).

@biomurph Thanks for the super-clear explanation. This makes sense. Do you know what happens to the sampling behavior when the transfer rate is lower than the specified sample rate? As in, does it skip samples, or wait to sample, or queue samples?…

@biomurph Finally got the firmware to upload via mpide. Not sure what is different; it still gave me a timeout but it landed and is functional. Now, want to help me get the effective sampling rate closer to the 500 sps I specified? Should that be …

Echo that; I set sampling rate to 500 sps but am topping out at about 295 sps. @rick, can you describe your solution in any more detail?

@biomurph Thanks. I'll let you know if anything interesting happens here. I already did the update procedure for the RFduino radios. Does pressing the RST button reset the RFduino radio firmware as well, or just the OpenBCI firmware?

@biomurphI've tried both the 1.5.8 and 1.6.5 versions of Arduino and had the same problem. When you compiled the prebuilt, was it on a 32 bit or 64 bit Windows OS? I wonder if that could be a factor? I couldn't tell if you meant you compiled it for…

@biomurphAlso, I was able to do a factory reset equivalent so I was at least able to get back to out-of-box functioning, which is better than nothing. However, I already lost track of what I did to do that! Can you remind me what does the factory re…

@biomurph Definitely have the right port. That's a reasonable thought given my description, however. Given that the sketch is only compiling to 508 bytes, something must be going wrong well before it tries to upload. I'm on Windows--is the Window…

@biomurph: Trying to follow the updates you indicate. The eventual goal is a version of the board firmware that increases the sample rate, though right now i would take any working firmware. Cannot get a firmware version to load in any setting. I …
