sp_blocking_read_next return 0

[patoskhy]

Dear

I have a problem with sp_blocking_read_next, it doesn't return anything. There is some configuration that should be considered for it to respond correctly.

I have msys64 installed, libserialport. in trasnbank-pos-sdc-c I run "make run example = poll".

If you have any advice, I would appreciate it.

Hi @patoskhy can you please try make debug example=poll

I have used doclight emulating the poll and this is result

I appreciate if you could help me

[afiebig]

It seems to me that the POS is not geting the message, are you sure it is in integrated mode and you are opening the right port?
