Pairing with Marshall Emberton 2

I’m unable to connect to speaker (Marshall Emberton 2)

Even tried resetting speaker

It is getting connected to all others devices

But whenever tried connecting it to NP2 it is saying passcode not match even of i start pairing from scratch from both devices

Reset network settings on your phone and then again reset the settings of your speaker and then try.

SiddheshShanbhag tried this and just about everything except a factory reset, which I cannot afford to do.
