not receiving proper WebSocket data

pavank

I’m trying to access data from web socket using smartapi-python, but I’m only receiving heartbeat data and some other data. Please do needful.

Request:
client_code="********" #client code is set in actual script
task="mw"
token="nsc_cm|15083"
ss = WebSocket(feed_token , client_code)
def on_tick(ws, tick):
for feed_data in tick:
print(feed_data)
def on_connect(ws, response):
print("connecting websocket")
print(task)
ws.send_request(token,task)

def on_close(ws, code, reason):
print("closing websocket")
ws.stop()

ss.on_ticks = on_tick
ss.on_connect = on_connect
ss.on_close = on_close
ss.connect( )

Note: login successful and feed token set

Response:
{'ak': 'ok', 'msg': 'connected', 'task': 'cn'}
{'ak': 'ok', 'msg': 'mw', 'task': 'mw'}
{'ak': 'ok', 'msg': 'heartbeat', 'task': 'hb'}
{'name': 'tm', 'tvalue': '12/03/2021 10:13:05'}
{'name': 'tm', 'tvalue': '12/03/2021 10:13:06'}

@admin facing same issue, only receving tm data

[{"tvalue":"16/02/2023 11:35:12","name":"tm"}]
[{"tvalue":"16/02/2023 11:35:13","name":"tm"}]
[{"tvalue":"16/02/2023 11:35:14","name":"tm"}]
[{"tvalue":"16/02/2023 11:35:15","name":"tm"}]

Here is code :

var ws =new websocket('', '',"nse_cm|2885", "mw");
ws.connection().then(() => {
ws.runScript("nse_cm|2885&nse_cm|1594&nse_cm|11536", "mw|sf|dp");
setTimeout(function () {
ws.close()
}, 30000)
});
ws.on('tick', receiveTick);

function receiveTick(data) {
	console.log(data);			  
}

@pavank did you get any solution of the problem? I am facing exactly same issue.

Hi @nirav said in not receiving proper WebSocket data:

sir i have install python sdk just tomorrow, so its a latest. till i getting heart beat. any solution for this by api team or not. my deadline is very close. suggest me asap

Hi nirav as discussed in the meeting we will update you on this.

rajanprabu

@nirav

Its hard to suggest with fewer details available. Are you running it on the cloud or at home with Wifi ? WiFi drop can also cause this.

tnx

rajanprabu

@nirav

This normally happens with network drop. If you are using new python SDK, you may potentially overcome this.

admin

HI @nirav we have noticed your query we will update you on this.

nirav

@admin
hii sir very good noon

tnx

@admin
Can you give any rough estimate when will you start streaming OI ?

James Bond

@nirav

No, OI is not streamed via WebSocket. It's yet to be added in WebSocket response.

@admin

@admin said in not receiving proper WebSocket data:

ws.send_request(token)

for SDK version 1.2.2 onwards this needs to be

ws.send_request(token,task)

where task is task="mw", #'mw'|'sfi'|'dp'

admin

@rajanprabu @ nirav
kindly generate feed token and use below code.

ss = WebSocket(FEED_TOKEN, CLIENT_CODE)

def on_tick(ws, tick):
print("Ticks: {}".format(tick))

def on_connect(ws, response):
ws.send_request(token)

def on_close(ws, code, reason):
ws.stop()

Assign the callbacks.

ss.on_ticks = on_tick
ss.on_connect = on_connect
ss.on_close = on_close

ss.connect( )`

rajanprabu

@nirav

can you please share the code and your sdk version ( if you are using python )

admin

Hi @nirav websocket is working fine from our end.

nirav

@admin ok sir tnx
I'm waiting for your answer.

pavank

@admin, i found the issue, in token i have misspelled nse_cm, but i think there should an error msg stating invalid token.................

admin

hi @nirav we have noticed your issue we will revert you back.
