esp32-c3 新建蓝牙服务问题

Postby Robert-qiao » Sun Aug 04, 2024 8:16 am

版本环境:ESP-IDF V5.2.2
根据例程新建一个服务后,增加第二个服务时,出现附件1问题,esp_log.h出现问题,当切换到V4.4.8版本时,编译无问题。
以下为源代码:

* This demo showcases creating a GATT database using a predefined attribute table.
* It acts as a GATT server and can send adv data, be connected by client.
* Run the gatt_client demo, the client demo will automatically connect to the gatt_server_service_table demo.
* Client demo will enable GATT server's notify after connection. The two devices will then exchange
* data.

esp-idf V5.0版本以上不支持打印uint32_t 类型数据,因为之前使用的是V4.3.4版本移植过来的,去除掉即可
