Cant Use The Test Code #5
Comments
|
Hum, that a very old project... not used anymore.
I would say
1) upgrade the digimat.espa module to the 0.1.14 version (just posted yet)
pip install -U digimat.espa
2) open a terminal on the same machine and run a local debug monitor with
"python -m digimat.logserver", assuming you have first installed the
"digimat.logserver" module (pip install -U digimat.logserver). Then start
your client (on the same machine). The client will forward logging through
a local tcpip connexion to the debugger monitor.
When you start your espa client, you should see something good/wrong on the
logger.
Maybe that your client simply can't open the com port. Start with 1 server
(only).
Good luck,
Frederic

… Hello,
I am new to ESPA 4.4.4. I started 2 virtual Serial Ports (COM29 and
COM30). Then i ran your test code and i see nothing happening even when i
send string data to COM29 or COM30. Could you please help ?
from digimat.espa import LinkSerial, Server, MultiChannelServer
class MyMultiChannelServer(MultiChannelServer):
def onNotification(self, notification):
print (notification)
if notification.isName('calltopager'):
print ("[%s]->paging(%s, %s)" % (notification.source,
notification.callAddress,
notification.message))
servers=MyMultiChannelServer()
link=LinkSerial('ts940', 'COM29', 9600, 'N', 8, 1)
servers.add(Server(link))
link=LinkSerial('espa2', 'COM30', 9600, 'N', 8, 1)
servers.add(Server(link))
servers.run()

Thank you very much for your response as it helped me further. I am trying to develop an ESPA 4.4.4 Client with Nodered and use your Project as the Server to test my Gateway. When i send the following message "1<ENQ>" as Buffer to the server i receive the following error

Hum, the string -> bytearray conversion seems to be buggy (this has been
done to migrate from python2 -> python3). This has not been tested, since
unused ;(
I have quickly pushed a fix (maybe?) but i can't test it -- not tested, not
working ;(
Could you try to upgrade the module version (.15) and retry to see if that
works ?

The Previous Problems seem to have been solved. Yet i dont receive any response from the server and i dont understand if i am sending the messages right. All I am doing currently is i am sending 1<ENQ>. is that normal to get no response even if the server wrote TX[04]? Could you maybe comment an example espa message that the server would expect ?
|
|
;) it seems that you send '1' (correct) and then 'E', 'N', 'Q' ... this is
not correct.
ENQ is a single char (0x5) !

Ok, same kind of python2->python3 error (bytearray/string)
I made a patch (.17), but this may be not the last one.

Thank you very much for the patches. how to use your code to send a message to another espa station ? even with threading it wont work.
|
|
came accross another bug :\
|

This module is a "espa server" so you have to use an espa client to send a
message to it.
When the server has received a message, it's up to you to dispatch it to
how you want.
This is not an espa client.
