Can I use nrf51 as a peripheral and nrf52 as a central device

[purgoufr]

Normally I am using nrf51 for peripheral(sdk 8.0.0 s110) and central(sdk10.0.0 s130) device. But I want to use nrf52 for just central device. I tried nrf52 for central(with sdk11.0.0 s132) device but it does not working. The problem is mismatch between nrf51 and nrf52?

Of course you can use nRF51 as a peripheral and nRF52 as a central, or the other way around, or any other BTLE capable chip or device or phone or anything else in any combination you like. It's BTLE, they all adhere to the spec, any device which adheres to the spec can communicate with any other device which adhers to it regardless of chip id, manufacturer or anything else.

So you just have a bug.
