Hello,
I have pushed the simtrace2 dummy message “hack” mentioned below to here:
https://gerrit.osmocom.org/c/simtrace2/+/26864
I do not necessarily intend for this to be merged. Rather, I wanted you to see what
workaround was applied.
Regards,
James

Subject: Simtrace2-tool communications issue
As an experiment: With the Atmel processor in this state, I modified simtrace2-tool to
send two commands back to back: a dummy message, followed by the real message. When I do
this, the first dummy message is dropped, as described above, but the second is executed
successfully! For some reason, you cannot get it to work by simply invoking
simtrace2-tool twice at the shell— critically, you have to send both messages without
closing and re-opening libusb in-between.
