WiFi Logger for esp32
Posted: Wed Apr 15, 2020 8:17 am
ESP32 WiFi logger - Log messages over WiFi, using either TCP, UDP or Websockets
- Generates log messages with same format as ESP-IDF Logging API.
- Can route logs generated by ESP_LOGX(), provides a custom function to log messages over wifi.
- Follows ESP-IDF log color pattern for different log levels.
- Using UDP as network protocol provides lowest latency.
- Minimal test condition - minimum free heap = 220388 bytes.
- TCP performance is mid-way:
- Minimal test condition - minimum free heap = 216537 bytes.
- Using Websockets provides the worst latency:
- Minimal test condition - minimum free heap = 205416 bytes.
