So far I know that is not possible. I think you need to debug it, do you
have maybe some kind of monitor interface to see what on the air?
When this happens randomly I had sometimes some corrupted data when the
spi clock is too high, but I think you use the bitbang gpio spi driver
now, or? Then I think the spi clock isn't the issue.
