1. Find parking sensor sound examples
2. Use sound editing software to extract single period of sound, software example
3. Replace sound1.mp3 with new sound and delete sound2.mp3

WARNING

• Pay attention to extracting single period of sound, like sound1.mp3 example, single period will be replayed with variable delay and simulate parking distance.
• Period shouldn't be longer than 100 ms, average 0:04 - 0:07 seconds, as shown at sound examples.

1. Build apk or download it from repo
2. Test application and try to crash it, in order to test communication, set

• IP address : 127.0.0.1
• Port: 4211

also turn on the volume to hear the bell.

UDP packet from ESP8266 to android has unused data:

• voltage2
• current

Remove data at both sides and recalculate new packet length and update constants.

Redesign APK UI, by:

• replace slider(bigger thumb button required)
• replace voltage1/voltage2/load text boxes with progress bars
• fix positioning and colors of all elements

Layout specifications are located under layout files and the rest of design properties are located under res folder.

Add more content about UDP protocol to documentation at Notion.

Make code for parsing 5 substrings from message, with & as a delimiter.

XXXX&XXXX&XXXX&XXXX&XXXX\0

voltage at cell 1 & voltage at cell 2 & current load & parking sensor distance & RSSI

Example:
Input: 3.8&3.936&6.936&50.32&76
Output: [3.8, 3.936, 6.936, 50.32, 76]
