Hi,

Are you using ws://smartapisocket.angelone.in/smart-stream for websocket 2.0 connection?

projectSB

@nagabhushant Well, I'm using WebSocket 2.0 from inside the Python SDK, as per the guidelines provided in the Github page.

@projectSB can you share the code i am not able to find the exact version

projectSB

@af I'm using the Websocket version 2.0 code as provided in this Github link:

https://github.com/angel-one/smartapi-python

This portion:

####### Websocket V2 sample code #######

from SmartApi.smartWebSocketV2 import SmartWebSocketV2
from logzero import logger

AUTH_TOKEN = "Your Auth_Token"
API_KEY = "Your Api_Key"
CLIENT_CODE = "Your Client Code"
FEED_TOKEN = "Your Feed_Token"
correlation_id = "abc123"
action = 1
mode = 1
token_list = [
{
"exchangeType": 1,
"tokens": ["26009"]
}
]
sws = SmartWebSocketV2(AUTH_TOKEN, API_KEY, CLIENT_CODE, FEED_TOKEN)

def on_data(wsapp, message):
logger.info("Ticks: {}".format(message))
# close_connection()

def on_open(wsapp):
logger.info("on open")
sws.subscribe(correlation_id, mode, token_list)

def on_error(wsapp, error):
logger.error(error)

def on_close(wsapp):
logger.info("Close")

def close_connection():
sws.close_connection()

Assign the callbacks.

sws.on_open = on_open
sws.on_data = on_data
sws.on_error = on_error
sws.on_close = on_close

sws.connect()

@projectSB see if this helps, I've added below code when I got a similar error

def on_data(wsapp, message):
        if message != b'\x00':
            #process data

af

@projectSB i have been getting same problem. but i got the solution. go to your on
smartWebscketV2.py and find this " def on_close(self, wsapp):
pass
" on your side the argument would be 4 in there make it like this. and thats it. it will work

Hello looks like i found solution !

use try: expect : in you on_data definition , looks like sometime in socket it is not able to decode stream and get close rather then printing error.

def on_data(wsapp, msg):
#print("Ticks: {}".format(msg))
try:
LIVE_FEED_JSON[msg['token']] = {'token' : msg['token'],'ltp' : msg['last_traded_price']/100 , 'timestamp' : datetime.fromtimestamp(msg['exchange_timestamp']/1000).isoformat()}
print(LIVE_FEED_JSON)
except Exception as e:
print(e)

@kishan9907 said in Websocket2.0 just stops after running for 1 min without any errors etc.:

if message != b'\x00':

Thanks! I have implemented this into my code. Hope this works!

projectSB

@Bhuva008 Thanks! will try this as well
