if I wanted to add an extra UART to a EGSx or even BGSx via SPI could I use a board like this? https://www.sparkfun.com/products/9981
Do you think it would perform reasonably well from Java? 9600 baud would be perfectly fine for my purposes.
Has anyone else done this?
The link points to 404 error.
Please remember that in BGSx and EHSx modules the same lines are common for SPI and ASC1 interfaces so if you connect an additional serial interface via SPI you will not have ASC1 interface. So there may be no point in using the additional SPI UART.
