Posted on November 14, 2017 at 14:52I've seen a few posts on issues with the SPI interface to the SPWF04 WiFi module, and from the past weeks experience have yet to get any of the examples supplied with the middle ware to actually work with SPI.
Eventually I want to use it with a STM32F7 processor but as there were no examples I bought a SRM32L476 Nucleo board so I could use the examples straight from the supplier unchanged.
Using the UART I got the Client Socket example to work quite quickly, but the SPI just hangs and the data I see at the PC is missing the first block that was supposedly written.
looking through the middleware SPI code there are many commented out 'debug' sections which were obviously used during development and a few worrying comments to put in random delays to get things to work.
So as you don't often see messages from users who got it working I'm trying to see if there are a great majority out there or is everyone using the slower UART interface method?
Is the SPI version of the middle ware actually commercial grade quality or should I write my own?
