Trouble with the TTGO T-Journal


i want to use the TTGO T-Journal as a camera for a project.

I followed this tutorial :

But had errors to do with not being able to access DMA or allocate memory.

I eventually found this, which worked :

The few examples that do exist for the t-journal often have different assignments for the camera pins, the above link is the only one that's worked for me so far.

Unfortunately it worked once, it still runs and creates a soft AP or goes into station mode but doesn't seem to be serving anything on port 80.

Are these devices flaky ? My ESP32-Cams all work fine.

Thanks, Gary.
