[Taler] Cashdesk with GNU Taler?

[Florian Jung]

Hi everyone!

I finally got my taler setup running so i can connect my android wallet 
to it, generate a withdrawal wire transfer subject, and use libeufin-cli 
to fake an incoming transaction on the exchange's bank account, so i 
actually can retrieve my talers in the wallet.


Now the next question is how do I give a customer some talers in 
exchange for real cash money. I see two options:

- The cash-desk-guy has a wallet and wallet-to-wallet-transfers the talers.

- I use the Taler Cashier app.


However, whenever I select "Send funds" in my wallet and try to send to 
a different wallet, i get:

"Let the payee scan this QR code to receive: 7001 (unexpected exception 
(message: insufficient balance)) [no QR code is displayed]"


What is the issue here? I definitely have enough balance in my "MANA" 
currency.


And when trying to use the cashier app, it wants to be connected to a 
bank api (e.g. https://bank.demo.taler.net/demobanks). What would I 
specify here? Can I point this to my libeufin sandbox or the nexus 
somehow (which URL specifically, and what credentials do I use for login?)



I use the debian bullseye packages and wallet v0.9.0 (20) if that helps


Best regards,

Florian
