[yousefmlotfy656]

hello dear , i found a problem with my code the after sometime i face a problems this is the serial monitor data chstate is 1 [415482][E][WiFiClientImpl.h:468] tcpWrite(): fail on fd 48, errno: 128, "Socket is not connected" [415484][E][WiFiClientImpl.h:468] tcpWrite(): fail on fd 48, errno: 128, "Socket is not connected" response payload read timed out [415500][E][WiFiClientImpl.h:468] tcpWrite(): fail on fd 48, errno: 128, "Socket is not connected" response payload read timed out [415512][E][WiFiClientImpl.h:468] tcpWrite(): fail on fd 48, errno: 128, "Socket is not connected" response payload read timed out [423483][E][WiFiClientImpl.h:468] tcpWrite(): fail on fd 48, errno: 128, "Socket is not connected" [423485][E][WiFiClientImpl.h:468] tcpWrite(): fail on fd 48, errno: 128, "Socket is not connected" response payload read timed out [423501][E][WiFiClientImpl.h:468] tcpWrite(): fail on fd 48, errno: 128, "Socket is not connected" response payload read timed out [423513][E][WiFiClientImpl.h:468] tcpWrite(): fail on fd 48, errno: 128, "Socket is not connected" response payload read timed out

i know that my internet connection not good enough but i want to make a stable code to reconnect again if any interuption happen in internet connection , so could you please help me in these part

this is my code , `/**

thank you dear.

After calling the RTDB function, if it gives the error, you can stop WiFiClient.

fbdo.stopWiFiClient();

I recommend you move to new library with simpler, faster and more reliable. https://github.com/mobizt/FirebaseClient

thanks for your response,

actually i didnt know where i should place the stop wifi client and do you think this will solve the payload problem?

[mobizt]

It is because session time out due to server terminates the connection.

You may have to stop WiFiClient when the RTDB function returns false at least every one minute to allow library to reconnect to the server as Google closed the session.

Thanks for your fast response , now i understand the problem but i didnt know what is the line of the rtdb function that returns false so please can you help me in this point (code)

thanks again.

[mobizt]

The function where fbdo was used.

Anyway, as I suggested, you should consider or prepare to move to new library,

The migration is not too difficult, but much reduce your code complexity.

[mobizt]

After you call to some function e.g. Firebase.RTDB.setString(&fbdo

If that function was called repeatedly for more than 1 minute, you may have to close the session (stop WiFiClient).

[mobizt]

Your code was suitable for async operation or using stream instead. https://github.com/mobizt/Firebase-ESP-Client/tree/main/examples/RTDB/DataChangesListener
