Sara,,
Thank you for your reply. Since I wrote the comment, I was able to successfully upload the sketch. I used the TTGO T1 board. I have a number of ports available:
Serial ports
/dev/cu.BLTH
/dev/cu.Bluetooth-Incoming-Port
/dev/cu.URT1
/dev/cu.usbmodem53190187981
/dev/cu.usbserial-143420
/dev/cu.wchusbserial143420
/dev/cu.wchusbserial53190187981
and it only worked with the last one.

I received a LILYGO® TTGO T-Journal ESP32 Camera Module Development Board today. I went through your excellent guide but when I try to upload the TTGO-T-Journal example from above, I get the following error:

ext section exceeds available space in board
Sketch too big; see https://support.arduino.cc/hc/en-us/articles/360013825179 for tips on reducing it.
Error compiling for board TTGO T1

Any suggestions?

My t-journal is working but after uploading the code it cn’t connect with the camera :

E (185) psram: PSRAM ID read error: 0xffffffff
E (328) cam_hal: cam_dma_config(280): frame buffer malloc failed
E (328) cam_hal: cam_config(364): cam_dma_config failed
E (329) camera: Camera config failed with error 0xffffffff
Camera init failed with error 0xffffffff

I’m wondering why it’s probing psram when there is none, i commented out the section of code referencing the PSRAM but still no detection of camera.

Hi.
Yes, the ESP32 chip comes with Wi-Fi and Bluetooth.

Hi everybody,

excellent tutorial, i managed to setup a working camera webserver basically without any experience with ESP32. Now i would like to try out some additional things…

So maybe you know if this Board also comes with Bluetooth? I looked at the specs, also on the Suppliers website, but it does not list Bluetooth. The specs do not list Wifi either, so perhaps its clear to most experienced people that Wifi and (hopefully) Bluetooth is standard here?

Thanks & best regards,
Markus

Thanks for the reply and suggestion however they seem to be directed to boards with PSRAM which the TTGO Journal doesn’t have. I have been able to get the original https://github.com/LilyGO/ESP32-Camera/blob/master/examples/ESP32_SoftAP_Cam/ESP32_SoftAP_Cam.ino to assemble and get work by substituting the ADAFRUIT SSD1306 library and code. So I know the board is still working. So it seem there must be something different in the difference in libraries.
By switching to the ESP32-PICO-D4 which the TTGO has the line ” E (530) psram: PSRAM ID read error: 0xffffffff” no longer appears, but Board: “ESP32 Wrover Module” is what is called for in the article. So I am wondering if there is some other parameter still missing from the newer library for this board. I have purchased the ESP Camera book and ESP Python books and looking forward to moving past this very annoying issue. The Adafruit SSD1306 demo does work.

TTGO Journal just arrived and I am trying to run the CameraWebServer example
on Arduino 1.8.14, I selected Partition Scheme “Huge App (3MB No OTH/1M SPIFFS)”
It loads but seems to halt with the following message. I wasn’t expecting it to be looking for PSRAM as it is a TTBO Journal board.
