Hello,
I work with Marc Wilson (recent poster here) and we have been trying to get remsim
functional. I got all of the client/server bits to finally talk to each other today along
with the port/slot mapping.
In my setup, the ST2 board is connected to a RPi running the remsim-client, and the PC/SC
card reader is mounted to an Ubuntu VM running the server/bankd components. I am running
the pieces each in their own shell so I can easily get stderr output.
Server VM:
@ubuntu:~$ sudo osmo-remsim-server

On the RPi running the client I get:

When I look at
https://git.osmocom.org/osmo-remsim/tree/asn1/RSPRO.asn
I see the setAtrReq PDU, so not sure why we are getting this error.
For completeness here is the pcsc_scan on the VM talking to the Reader+Card that I am
trying to remote:
@ubuntu:~$ pcsc_scan
Using reader plug'n play mechanism

I could really use some help. I am so close to getting this functional but stuck on this
snag.
Thank you,
