As for burning a bootloader, it should be straightforward using a SPI-arduino type bootloader example sketch. Beware however, if you have an older miniwireless, you need to guard against SPI contention during bootload, as it is a shared bus. The older miniwireless does not have a chipselect pullup on the SPI memory or SPI radio, so it is important to give these two GPIO's at least a weak pullup so there is no SPI contention during bootloading. Let us know which bootloader you are using. We need to update our default bootloader, but would like to hear suggestions from our customers as to the preferred choice. I think Papa has some decent traction going on with wireless bootloading, and it might be good to target this bootloader---especially if it can be supported by some default Arduino IDE board selection. If not, then I suppose it's still okay with clear instruction for customers. Thanks for your forum participation.
