How to troubleshoot network connecction issue

fring · July 21, 2023, 2:30pm

My LoRa32 V2.1_1.6 with OMG ver 1.6 stops responding after a while.
I suspect network issues.
How do I troubleshoot? Is there any logging available?
Can I configure it to use static IP, instead of DHCP? How?

Hi @fring

have a look at this section in User_config.h

github.com

1technophile/OpenMQTTGateway/blob/development/main/User_config.h#L67


      
          #  define Gateway_Name "OpenMQTTGateway"
          #endif
          #ifndef Gateway_Short_Name
          #  define Gateway_Short_Name "OMG"
          #endif
          
          #ifndef Base_Topic
          #  define Base_Topic "home/"
          #endif
          
          /*-------------DEFINE YOUR NETWORK PARAMETERS BELOW----------------*/
          
          //#define NetworkAdvancedSetup true //uncomment if you want to set advanced network parameters, not uncommented you can set the IP and MAC only
          #ifdef NetworkAdvancedSetup
          #  if defined(ESP8266) || defined(ESP32)
          const byte ip[] = {192, 168, 1, 99}; //IP address of the gateway, already defined for arduino below
          #  endif
          const byte gateway[] = {0, 0, 0, 0};
          const byte Dns[] = {0, 0, 0, 0};
          const byte subnet[] = {255, 255, 255, 0};
          #endif

for using static IP.

What make of router do you have, and are you able to view any router logs of possible reconnection/DHCP lease renewal issues?

The router is an “Asus RT-AC2900”.
The only thing I can see from the router log is:

No really sure if this is similar to the WiFi disconnection/re-connection problems I have been seeing with my router, but could you test it by building with using the older platform by swapping out

esp32_platform = espressif32@6.1.0

with

esp32_platform = espressif32@3.5.0

in the platformio.ini file, and let us know if it makes any difference?

Or alternatively with the above mentioned static IP assignment.

I also started a test build, which is available at

with SHA: 7f74a6, until it gets overwritten again by the nightly build in a few hours.

Ok, I have deployed with static IP, now.
Let’s wait and see how it works out.

This is still an issue.
The gateway always stops responding after an uptime of 130 000-140 000 seconds.

How is the memory looking on this same time range ?
