I need to communicate with a device via RS-485 that support iec 62056-21 protocol.
Does someone have tried this?
I need some documentation or c++ library to comunicate with this… :-)
A quick Google search turns up a reference [qtforum.org] of somebody using QextSerialPort for a RS-485 device. So, that should work, I guess. That, of course, does not implement iec 62056-21 on top of that yet. Does that get you started? Note that I don’t have personal experience with any of this :-)
I already know QextSerialPort and I have no problem in communicating via rs-485. My problem is to know iec 62056-21 .
Reading some manuals it seems that iec 62056-21 is a standard protocol but I can’t find some documentation about.
I only found this [satec-global.com] IEC 62056-21.pdf but it’s for a specific device and I actually can’t try that protocol for my device.
