  • This is a great way to program boards with no additional cost per PCB. I've been doing this on my own boards for a few years, and it works great. My adapter board uses the standard ISP header as input, and spits-out the pogos in the same arrangement : http://bitpuppy.com/Bitpuppy.Bed.of.Nails.ISP.Programming.Adapter.htm

  • I just wanted to share my experience with using the RN42 and RN41 at high [115k+] data rates. It may apply to lower rates, but I haven't tested. These devices seem to disconnect from the BlueTooth host after communicating for a short period [in some cases less than 1 sec]. After some trial-and-error, I realized that the power supply needs decent bulk capacitance. I didn't test exhaustively for the optimal cap value, but bypassing power via a low-ESR 470uF capacitor totally stabilized my module. Now it works all of the time.

    Hope this saves someone else some aggravation.

No public wish lists :(
