SPIClient client response messages are shredded and useless, but here is how i fixed it.

hi.

i know, this must sound strange to you hardcore, die hard SPI people. but i just disconnected CS and now the response message (all 32-byte) from slave to master will get delivered. it looks a bit funny from the logic analyzer perspective, because it can't detect the boundaries correctly but the data are where they should be.

if just two mcu's talk to each other via spi, this is a work around. i still have some hope left for a real fix but till then, the bluepill master is very happy with the ai thinker esp-12f.

oh, and the gpio15 problem got also solved, just leave it unconnected.

please suggest me a better solution &

thanx for your good work.
