I've built the 0.12.1 Monero Core release and tried to create the wallet from my Ledger Nano S on device, but get the following error:
Error: failed to generate new wallet: Fail SCard API : (-2146435069) Invalid handle. Device=0, hCard=0, hContext=1
Things I have done:
- Set up the SmartCard service as much as I could from the instructions from Ledger Github instructions. I was able to carry out steps 1 to 3 successfully (the file existed for me to ultimately edit). However, note that I am using Mac OS 10.13 and there is no SmartCard installer for 10.13 from the link supplied in the instructions. The 10.12 installer didn't work. Maybe I don't have SmartCard service installed?
- had the Ledger Nano S on Beta 0.12.4 installed.
- had the Monero app active on the Ledger Nano S on before trying to create the wallet.
