# Sylvia Touch Relay
|
||||||
|
|
||||||
|
BLE-gestuurde relais-switch voor de M5Stack Atom VoiceS3R (ESP32-S3) met een bijbehorende Android-app. Het relais kan worden bediend via een capacitieve touch-sensor (open-drain) óf via Bluetooth Low Energy vanaf een Android-telefoon.
|
||||||
|
|
||||||
|
## Hardware
|
||||||
|
|
||||||
|
| Component | Details |
|
||||||
|
|---|---|
|
||||||
|
| Board | M5Stack Atom VoiceS3R (SKU: C126-ECHO) |
|
||||||
|
| SoC | ESP32-S3-PICO-1-N8R8 (8MB Flash, 8MB PSRAM) |
|
||||||
|
| Touch sensor | Open-drain sensor op **G38** (3.3V, interne pullup) |
|
||||||
|
| Relais / LED | Op **G1** (3.3V GPIO output) |
|
||||||
|
| Status LED | Op **G46** (knippert 3x bij opstarten) |
|
||||||
|
|
||||||
|
### Pinout (Atom VoiceS3R onderste header)
|
||||||
|
|
||||||
|
```
|
||||||
|
G38 G39 3.3V GND 5V G5 G6 G7 G8
|
||||||
|
```
|
||||||
|
|
||||||
|
- **G38** — Touch sensor input (active LOW, interne pullup ingeschakeld)
|
||||||
|
- **G1** — Relais output (HIGH = aan, LOW = uit)
|
||||||
|
- **G46** — Status LED (3x knipperen bij opstarten, daarna uit)
|
||||||
|
|
||||||
|
### Aansluiting
|
||||||
|
|
||||||
|
```
|
||||||
|
Sensor GND → GND
|
||||||
|
Sensor OUT → G38
|
||||||
|
Sensor VCC → 3.3V
|
||||||
|
|
||||||
|
Relais + → G1
|
||||||
|
Relais - → GND
|
||||||
|
```
|
||||||
|
|
||||||
|
> **Let op:** De ESP32-S3 interne pullup is ~45kΩ. Bij lange draden of elektrische ruis een externe 4.7kΩ–10kΩ pullup naar 3.3V plaatsen.
|
||||||
|
|
||||||
|
## Firmware
|
||||||
|
|
||||||
|
De firmware is geschreven in C++ met behulp van PlatformIO en de Arduino-framework. BLE wordt verzorgd door de ESP32 BLE library.
|
||||||
|
|
||||||
|
### Logica
|
||||||
|
|
||||||
|
Het relais gaat aan als **één van beide** bronnen actief is:
|
||||||
|
|
||||||
|
| Bron | Voorwaarde | Resultaat |
|
||||||
|
|---|---|---|
|
||||||
|
| Touch sensor | G38 = LOW (aanraken) | Relais aan |
|
||||||
|
| BLE command | App stuurt `0x01` | Relais aan |
|
||||||
|
| Geen van beide | G38 = HIGH + geen BLE command | Relais uit |
|
||||||
|
|
||||||
|
De touch sensor en BLE werken onafhankelijk. Als de sensor losgelaten wordt én de BLE-knop niet ingedrukt is, gaat het relais uit.
|
||||||
|
|
||||||
|
### BLE GATT
|
||||||
|
|
||||||
|
| Eigenschap | UUID |
|
||||||
|
|---|---|
|
||||||
|
| Service | `4fafc201-1fb5-459e-8fcc-c5c9c331914b` |
|
||||||
|
| Characteristic | `beb5483e-36e1-4688-b7f5-ea07361f26d8` |
|
||||||
|
|
||||||
|
De characteristic ondersteunt `WRITE` en `NOTIFY`. Schrijf `0x01` om het relais aan te zetten, `0x00` om uit te zetten.
|
||||||
|
|
||||||
|
### Serial monitor
|
||||||
|
|
||||||
|
Baudrate: **115200** (USB CDC). De firmware stuurt heartbeat-statussen elke 5 seconden en logt statuswijzigingen:
|
||||||
|
|
||||||
|
```
|
||||||
|
=== Atom VoiceS3R BLE Relay ===
|
||||||
|
LED blink done, starting BLE...
|
||||||
|
BLE: advertising started as 'AtomS3R-Relay'
|
||||||
|
Setup done.
|
||||||
|
[heartbeat] relay=OFF touch=no ble=disconnected
|
||||||
|
BLE: device connected
|
||||||
|
Relay ON (touch=YES, ble=connected)
|
||||||
|
Relay OFF (touch=no, ble=connected)
|
||||||
|
```
|
||||||
|
|
||||||
|
### Uploaden
|
||||||
|
|
||||||
|
> **Download-mode:** Houd de reset-knop ~2 seconden ingedrukt tot de groene LED aangaat, laat dan los. Het board is nu in download-mode.
|
||||||
|
|
||||||
|
```bash
|
||||||
|
pio run --target upload
|
||||||
|
```
|
||||||
|
|
||||||
|
Na het uploaden treedt er een harde reset op. Als het board in download-mode blijft, USB eruit/erin of kort op reset tikken om in run-mode te komen.
|
||||||
|
|
||||||
|
## Android App
|
||||||
|
|
||||||
|
### Features
|
||||||
|
|
||||||
|
- **Auto-connect:** De app scant automatisch bij opstarten naar het BLE-apparaat "AtomS3R-Relay"
|
||||||
|
- **Auto-reconnect:** Bij wegvallen van de verbinding wordt na 2 seconden opnieuw gescant
|
||||||
|
- **Hold-to-activate:** Houd de knop ingedrukt voor relais aan, loslaten voor relais uit (zelfde gedrag als de sensor)
|
||||||
|
- **Permissies:** Vraagt BLUETOOTH_SCAN, BLUETOOTH_CONNECT en ACCESS_FINE_LOCATION aan (Android 12+)
|
||||||
|
|
||||||
|
### Bouwen
|
||||||
|
|
||||||
|
Vereisten:
|
||||||
|
- Android SDK (API 34+)
|
||||||
|
- Java 21
|
||||||
|
- Gradle 8.5
|
||||||
|
|
||||||
|
```bash
|
||||||
|
cd android
|
||||||
|
JAVA_HOME=/pad/naar/jdk21 ./gradlew assembleDebug
|
||||||
|
```
|
||||||
|
|
||||||
|
De APK staat na build in `android/app/build/outputs/apk/debug/app-debug.apk`.
|
||||||
|
|
||||||
|
### Installeren
|
||||||
|
|
||||||
|
```bash
|
||||||
|
adb install -r android/app/build/outputs/apk/debug/app-debug.apk
|
||||||
|
```
|
||||||
|
|
||||||
|
Of via draadloze foutopsporing:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
adb connect <ip>:<poort>
|
||||||
|
adb install -r android/app/build/outputs/apk/debug/app-debug.apk
|
||||||
|
```
|
||||||
|
|
||||||
|
### UUID's
|
||||||
|
|
||||||
|
De app gebruikt dezelfde UUID's als de firmware:
|
||||||
|
|
||||||
|
```kotlin
|
||||||
|
private val SERVICE_UUID: UUID = UUID.fromString("4fafc201-1fb5-459e-8fcc-c5c9c331914b")
|
||||||
|
private val CHARACTERISTIC_UUID: UUID = UUID.fromString("beb5483e-36e1-4688-b7f5-ea07361f26d8")
|
||||||
|
```
|
||||||
|
|
||||||
|

## Technische notities
|
||||||
|
|
||||||
|
- De Atom VoiceS3R gebruikt de ES8311 audio codec op G45/G0/G48/G4/G3/G17/G11, IR TX op G47, en de knop op G41. Deze pinnen zijn niet beschikbaar voor eigen gebruik.
|
||||||
|
- G1 en G2 zitten op de HY2.0-4P Grove poort. G5-G8, G38, G39 zitten op de onderste expantie-header.
|
||||||
|
- De firmware gebruikt geen M5Unified library — alleen Arduino core + ESP32 BLE. Dit maakt de serial output betrouwbaarder via USB CDC.
|
||||||
|
- `ARDUINO_USB_CDC_ON_BOOT=1` is ingeschakeld voor virtuele serial via USB.
