Help with usage of library

[dronecz]

Hi @washo4evr

I want to use your library with this project #https://github.com/cheton/cnc and I opened this issue: #cncjs/cncjs#42. In short I want use your library but I can not send/ I don´t know how to send right sequence to server. Could you please look at that issue and help me with this?

Many thanks for reply.

Hey,

I will give it a look over the weekend
Im sure you can use my library for that project

We will figure it out

hi
did you try running the example provided with the library?
the process is pretty straightforward
you need to use client.send("");
all the parsing happens on the server to save memory on the ESP8266
we could work on a step by step together if you want

Hi,

to be honest I did not tryed your example because I don´t have accout at Sparkfun and I think is not really necessary to have one just for one test.
I don´t know if you had time look at that issue, but I can connect to server, I can send client.send("command","/dev/ttyAMA0", "reset"); but syntax is not right. When I look how is writen client for server, at first client send client.send('list'); to receive list of devices which can be used, and after that I will probably know what I should send. If I try compile my code with client.send('list'); I got error beacuse it is not implemented in your library. I´m very interested in this so we can try step by step ;-). I´m more HW than SW man so please be patient with me ;-), thanks.

P.S. : I posted wrong link for my issue in other project so I repaired it.

Hi @washo4evr

some time past and I got back with my project and I made some progress with it.
I can now use your library and connect my NodeMCU to Node.js server, and if I send this command:
client.send("list","",""); to the server I got back this reply: "serialport:list",[{"port":"/dev/ttyAMA0","inuse":false .
So far so good, but when I want move on and send this: client.send("open","/dev/ttyAMA0","115200"); I got this reply from the server: Invalid "baudRate" must be a number got: undefined , so my question is, can I tell it that this data is number?

Many thanks for help.

Hi,
do you have the code of the server
that would help a lot
plus, in ""serialport:list",[{"port":"/dev/ttyAMA0","inuse":false"
the baudrate is not even mentioned
that is weird

Hi @washo4evr

you can look at code here: https://github.com/cheton/cnc. I don´t think that´s problem because that command is just for listing availaible ports on server. I can send more printscreens if you want.

Thanks

heya,
screenshots would be great too
I will have more time this weekend to go over them

Hi @washo4evr ,

you want screenshot of server side or client side?

Edit:

Here is server side:
