@Lindsay-Wright Theoretically you could put variation of the Linkit Smart OpenWrt build on them which should have the patch to switch SPI to half-duplex mode and thus avoid the bit corruption due to a hardware issue with full duplex. But that is obviously a bit of a non-trivial project - ultimately, it just resemphasizes the problem pointed out long ago, that Onion's persistent refusal to release sources which build to a system with working wifi means that the community can't fix little problems for them, and all the work of fixing everything falls on their overstretched team. Another approach you could consider would be to bit-bang SPI, or use a small MCU to bridge to it from I2C or a spare UART.
