feat: 启用BLE蓝牙图片传输 + 移除温湿度传感器代码
1、app_main 中新增 ble_init() 调用,启动 BLE GATT Server(设备名: MY-BLE) 2、移除 temp 模块:CMakeLists.txt、main.c、pages.c 中的引用和 temp_test() 函数 3、精简 ble.c:移除 SENSOR_SERVICE(温湿度服务)、TEMP/HUMI 特征、READ_EVT 处理,仅保留图片传输服务 4、新增项目性能分析报告(N16R8 模组资源消耗详细分析) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

||||
- `CONFIG_BT_ALLOCATION_FROM_SPIRAM_FIRST=y`:BLE 动态分配优先使用 PSRAM,减少内部 SRAM 压力
|
||||
- BLE DIRAM 占用仅 ~15 KB(得益于 PSRAM 分流)

## 七、资源余量评估
|
||||
|
||||
### 7.1 关键资源余量
|
||||
|
||||
| 资源 | 当前占用 | 总量 | 剩余 | 余量评估 |
|
||||
|------|----------|------|------|----------|
|
||||
| **内部 SRAM (DIRAM)** | 180.6 KB (54.1%) | 333.8 KB | **153.2 KB** | 充裕,可支撑更多功能 |
|
||||
| **IRAM** | 16.0 KB (99.99%) | 16.0 KB | **1 B** | 已满,但正常(ESP-IDF 自动管理溢出到 Flash) |
|
||||
| **App Flash** | 1,359 KB (33%) | 4,096 KB | **2,737 KB** | 非常充裕 |
|
||||
| **总 Flash** | ~6 MB (分区) | 16 MB | **~10 MB** | 极其充裕 |
|
||||
| **PSRAM** | 运行时动态分配 | 8 MB | ~7.5+ MB | 极其充裕 |
|
||||
|
||||
### 7.2 IRAM 满载说明
|
||||
|
||||
IRAM 99.99% 是正常现象:
|
||||
- ESP-IDF 的链接脚本会自动将溢出的 IRAM 代码放到 Flash 中执行
|
||||
- 只有标记为 `IRAM_ATTR` 的关键中断处理函数才必须在 IRAM
|
||||
- 不影响正常运行,无需优化
|
||||
|
||||
### 7.3 运行时内存估算(满负荷)
|
||||
|
||||
| 项目 | 预估消耗 | 来源 |
|
||||
|------|----------|------|
|
||||
| FreeRTOS 任务栈 (5-6个任务) | ~30 KB | DIRAM 堆 |
|
||||
| LVGL 帧缓冲 (双缓冲) | ~43 KB | PSRAM |
|
||||
| LVGL 对象树/样式 | ~20 KB | DIRAM 堆 |
|
||||
| BLE 连接管理 | ~10 KB | PSRAM (优先) |
|
||||
| JPEG 解码临时缓冲 | ~15 KB | 堆 (临时) |
|
||||
| SPIFFS 缓存 | ~4 KB | 堆 |
|
||||
| **合计** | **~122 KB** | |
|
||||
| **DIRAM 堆剩余** | **~153 KB** | 满足需求 |
|
||||
|
||||

|
||||
|
||||
## 八、总结
|
||||
|
||||
**N16R8 模组资源完全满足当前项目需求**:
|
||||
|
||||
1. **Flash (16MB)**:固件仅用 1.36 MB,SPIFFS 2 MB,大量空间可扩展 OTA 或增加图片存储
|
||||
2. **内部 SRAM (512KB)**:DIRAM 占 54%,剩余 153 KB 足够运行时动态分配
|
||||
3. **PSRAM (8MB)**:BLE 动态内存优先使用 PSRAM,有效降低内部 SRAM 压力,剩余 7+ MB
|
||||
4. **BLE 影响可控**:BLE 增加约 277 KB Flash + 15 KB DIRAM,对 N16R8 影响微乎其微
|
||||
|
||||
**优化建议**(可选):
|
||||
- 如需进一步减少 Flash 占用,可考虑压缩 UI 内嵌图片资源(当前 ~333 KB)
|
||||
- 如需启用 WiFi + BLE 共存,DIRAM 仍有足够余量
|
||||
- PSRAM 可用于存储更大的 JPEG 解码缓冲,提升图片切换速度
