# AWS ESP 32 Cam
## Setup
[Download the AWS Root CA](https://www.amazontrust.com/repository/AmazonRootCA1.pem)
Create your AWS Certificates with
```bash
aws iot create-keys-and-certificate \
--set-as-active \
--certificate-pem-outfile \
--public-key-outfile \
--private-key-outfile
## Example
aws iot create-keys-and-certificate \
--set-as-active \
--certificate-pem-outfile "iot_cert_demo.pem" \
--public-key-outfile "iot_cert_demo.key" \
--private-key-outfile "iot_cert_demo.private"
```
Get your AWS IoT endpoint URL with `aws iot describe-endpoint --region us-east-1`
Your certificates will need to be formatted with newline characters. For example your CA Certificate would look like.
```bash
const char CA_CERT[] ="-----BEGIN CERTIFICATE-----\n"
"MIIDQTCCAimgAwIBAgITBmyfz5m/jAo54vB4ikPmljZbyjANBgkqhkiG9w0BAQsF\n"
"ADA5MQswCQYDVQQGEwJVUzEPMA0GA1UEChMGQW1hem9uMRkwFwYDVQQDExBBbWF6\n"
--snip---
"-----END CERTIFICATE-----";
```
Modify `lib/conf/conf.h` with your variables.
### Flashing Code
When flashing code you will need to hold the button connected to ```IO0``` and ```GND``` down. If you run into this issue then you will need to press the button on the back of the EPS32-CAM once.
```bash
Connecting........_____....._____....._____....._____....._____....._____....._____
A fatal error occurred: Failed to connect to ESP32: Timed out waiting for packet header
*** [upload] Error 2
```
### Monitoring Via Serial Port
When monitoring code via the serial port you will need to make sure the button between ```IO0``` and ```GND``` is not held down. If you still do not see anything then press the button on the back of the ESP32-CAM once.
### Monitoring MQTT topic
I tend to use [MQTT/.fx](https://mqttfx.jensd.de/) to monitor the MQTT topic without needed to log into AWS. You will need to include your ```Client Key File``` ```AWS Root CA``` and ```Client Certifiate File``` in your conection profile settings.
