# RobonectCam

## Objectives

### Attach a bigger and stronger antenna

- Antenna: https://www.amazon.de/gp/product/B0895ZQ7CV/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1

- Tutorial for switching to an external antenna: https://randomnerdtutorials.com/esp32-cam-connect-external-antenna/

- The connection is a tiny SMD resistor that has to be shifted. Horrible to do with a big-tipped soldering iron. Should've brought my own :(

### Read WiFi credentials from SD card

- If I compile the credentials into the uploaded code, it has to be completely recompiled when for example the WiFi crendetials change

- Therefore I'll just read them for SD card so that one can just change the `wifi_credentials.h` file on the card

- https://randomnerdtutorials.com/esp32-microsd-card-arduino/

  - Format SD card to FAT32

## Considerations

- WiFi credentials shouldn't be hardcoded and under GIT but dynamically loaded from a SD card.

  --> That way, Olli can just replace the SD card when he changes the WiFi name/pwd

- Can I request a permanent IP inside the WiFi without problems? Maybe just send a mail to Olli upon successful connection

- Can I turn bluetooth off to save energy?

### 3D

- "Official" Robonect Cam Holder: https://www.robonect-shop.de/downloads/sonstiges/

- Model for the ESP32 Cam chip: https://grabcad.com/library/esp32-cam-1

- Model for the Antenna: https://grabcad.com/library/antenna-9

## Issues

### The ESP32-Cam has no USB port

- USB32-Cam: https://www.amazon.de/gp/product/B08MZV1TT9

- Due to the lack of an USB port, I have to use an FTDI programmer (https://www.amazon.de/gp/product/B01N9RZK6I)

### How can I change the BAUD rate in PlatformIO?

- Added `monitor_speed = 115200` to the `platformio.ini` file

### Why is the serial montior now showing anything?

- Did you disconnect `GPIO O` from `GND` ?

- https://community.platformio.org/t/solved-esp32-serial-monitor-not-working/2858/7

  -->Added `monitor_rts = 0` and `monitor_dtr = 0` to the `platformio.ini` file
