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

35014 DLINP NOTICE input/ipa.c:283 0.0.0.0:9998 accept()ed new link from 127.0.0.1:36289

@ubuntu:~$ sudo osmo-remsim-bankd -b 1 -n 1

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!
