Installing and Using OpenWrt

Hi @spamcop and all,

I installed curl and ran this command in your script. It seems like 192.168.225.1 is not responding

root@OpenWrt:~# curl -v -d '{"module":"status", "action":"0"}' -H "Content-Type:
 application/json" http://192.168.225.1/cgi-bin/qcmap_web_cgi
* Failed to connect to 192.168.225.1 port 80 after 131855 ms: Error
curl: (28) Failed to connect to 192.168.225.1 port 80 after 131855 ms: Error

ping 192.168.225.1 is not responding either

My router is tp-link mr6400 and it's very similar to mr200

My version of curl is:

root@OpenWrt:~# curl -V
curl 8.8.0 (mipsel-openwrt-linux-gnu) libcurl/8.8.0 mbedTLS/3.6.0 nghttp2/1.62.1
Release-Date: 2024-05-22
Protocols: file ftp ftps http https ipfs ipns mqtt
Features: alt-svc HSTS HTTP2 HTTPS-proxy IPv6 Largefile SSL threadsafe UnixSockets

I appreciate any help here

My LTE IP address is 192.168.1.1

Tried this and the web server returned 404 :frowning:

not similar enough, it seems.

Hi,

Calling uqmi -s -d /dev/cdc-wdm0 --get-signal-info in a script that loops will crash the script if another process calls uqmi according to this:

I did try the uqmi script here:

It works but after some time the script stops running :frowning:
