Hi ,All

We use the wifi and connect to AP .

We want to download file to the http server.

After connection ,it will send write request,and then receive the request in the http server and response OK.

But when we need to read the response from server to our board ,it will send

"[w_tmr] Starting timer: 20219A60 for 800 mS
read
[w_tmr] Error: Unable to start timer"

What happen the WiFi timer ?

log :

Hi @danielchen

We use the wifi station mode to connect to the external http server,and set the socket setting.

After connecting to socket,send the get request to server can successfully,but it will happen problem when read response from server.

Get request is for download file , file size about 700 KB.

When we use get request for other small file(.txt),it can read file content ,so we make sure http server is ok and it actually connect to server .
