Is there any difference between nRF52832-QFAAB0 and nRF52832-QFAAE0?
Yes, there are some differences. E0 is a new chip revision, but still drop-in compatible with SW built for B0. See informal notice here for more details: http://infocenter.nordicsemi.com/pdf/in_105_v1.0.pdf
Is it possible to use the light switch provision example with B0 chip? Also e0 chip is QFAA-? Did you start far?
Yes you can run the same SW on both E0 and B0 (compatibility matrix)
