Circuit

The suitcase consists of switches and LEDs only, its pretty simple:

Switch / Push Buttons:

• GPIO Input should be grounded via 1.5k Ohm
• GPIO Input enable should be 3.3V via 1k Ohm

      |
      |       \
 GPIO |--+--o  o ---[1k Ohm]--- 3v3

      |      |
      | 1.5k |
      |______|
         |
        GND

Feedback LEDs:

All LEDs should be connected to 3v3 via 110 Ohm resistors

Configuration

Execute make and set WIFI / Jenkins properties.

If properties are already set in sdkconfig, do make menuconfig, then navigate to Jenkins Trigger Configuration section.

HTTPS configuration

Run the following command:

$ openssl s_client -showcerts -connect www.howsmyssl.com:443 </dev/null

and place the Root CA cert into main/server_root_cert.pem

Go to main/include/jenkins.h and define JENKINS_ON_HTTPS.

Optional

• Set HTTP request timeout in main/include/http.h in case your Jenkins instance is slow (default is 5 seconds)
• Set Retry Count and Interval in main/include/jenkins.h in case jobs are spending too much time in the Queue. Look for RETRY_JOB_NUMBER and DELAY_BEFORE_RETRY.

Then deploy application to ESP32 device
