BPA interactions with non-BPA

[usingtechnology]

Just wanted to start a discussion and and an area to put in any findings we have using the BPA with non-BPA agents.

I have walked through using BPA with Trinsic Wallet - phone app and esatus wallet - phone app.

I have walked though using Trinsic Studio (in place of BPA), Trinsic Wallet and esatus wallet for comparison.

I have also used the BPA connected with Trinsic Studio to see their interactions.

Trinsic is Aries (based on Aries Framework .NET), but not aca-py. They do have their own API but I just used the interfaces to do the interactions. (I did have to add in new code to BPA to accept/receive invitations - see PR 585)

A few notes around set up of Trinsic Studio (https://trinsic.studio/) to act like a BPA.

I upgraded to a Developer Account (allowed me to change to Canada Region). Not sure if the region mattered, but upgrading allowed me to change region (really more useful to up the count of credential exchanges allowed per month).

I deleted both esatus and trinisic wallets from my phone, then reinstalled new empty ones.
Connected both phone wallets to BCovrin Test Ledger (esatus is BCGov Test Ledger).

Turned off Wifi on my phone.

Will add more tomorrow...

This is BPA and Trinsic Studio.
Was having issues creating schema/cred defs (I had previously done it, so put a question out to Trinsic support).
Wallet is only API accessible, so studio is ok (out of box) for issue and verify, not holder.
Marked stuff that is API with "?" as Studio doesn't have the function directly, but some things can be achieved using the API.
