    • 请问如何协商BLE的连接参数

      代码里好像没有看到初始配置的接口

      // Link parameter update success event
      typedef struct
      {
      uint8_t conidx; //!< Connection index
      uint16_t con_interval; //!< Connection interval
      uint16_t con_latency; //!< Connection latency value
      uint16_t sup_to; //!< Supervision timeout
      }gap_evt_link_param_update_t;

    • RE: 需要一个彻底关断UART调试输出的方法

      你好，我们目前用到了所有的I/O，请问这样重定位是否有影响？

    • 需要一个彻底关断UART调试输出的方法

      我们的项目用到了所有的I/O，所以UART调试是复用的，当前UART日志的输出都是通过接口 co_printf ，建议开放该接口

      直接用一个什么都不执行的语句宏定义替代 co_printf，同时关闭休眠时UART的配置 ，发现有一个软件特性会受到影响，还没找到原因，理论上应该没影响才对

      比如直接输出VBAT？

    • llc_write_bytes 接口好像有问题

      0_1583314359185_f6ae53bd-d054-4443-bba5-afdfe9d4c956-image.png

      研究IIC接口，API写的有点怪，因为我有个器件操作是没有REG ADDR的，所以还要修改API

      这个多字节写的API，buffer 这个操作，感觉有问题，可能会越界，我只是看，因为板子还没回来，还没有调试

    • RE: 请教低功耗管理

      上述已经解决，是system_sleep_disable引起的，注释掉可以到7个uA

      新问题：系统如何进入POWER OFF mode呢？

    • 请教低功耗管理

      使用本周的SDK

      使用 example/dev1.0/ble_multi_role 工程
      编译使用 GNU ARM GCC 6.2

      为了测试低功耗，把如下函数做了屏蔽，也就是软件不做任何事
      void user_entry_after_ble_init(void)
      {
      co_printf("BLE Multi Role\r\n");

          co_printf("POWER SAMVE EN:%d\r\n", __jump_table.system_option&SYSTEM_OPTION_SLEEP_ENABLE);



// User task initialization, for buttons.
//user_task_init();

// Application layer initialization, can included bond manager init, 
// advertising parameters init, scanning parameter init, GATT service adding, etc.    
//multi_role_init();

      }

      硬件板子采用电池供电，拔掉 3V3_LDO的跳线，因为我还不知道如何关闭这个LDO，软件默认是打开的

      运行结果：
      1）系统重启后能进入低功耗，电流为 7uA左右
      2）过上20s左右，系统会退出低功耗，电流为 3mA左右，再也进入不了低功耗

      问题：为什么会出现2）

      测试2：如果让BLE进入广播模式，系统无法进入低功耗模式，使用原始的广播配置。

      问题：为什么这个时候无法进入低功耗？

    • 请问如何在启动阶段判断CHG引脚是否在充电？

      实际测试，充电器在位，在RESET开机阶段，PMU这个中断的上报是概率的
      attribute((weak)) attribute((section("ram_code"))) void charge_isr_ram(uint8_t type)

      问题1：请问有没有读取充电接口状态的接口或者寄存器？
      问题2：开启和关闭充电，以及电流是否软件无需控制？

    • RE: 20200227下载的SDK使用GCC ble_simple_peripheral编译不过，其他project可以编译通过

      当前我再使用 dev1.0/ble_multi_role 工程做开发，这个工程是没问题的。 但我看好像只有ble_simple_peripheral支持开发板所有的 外设功能，使用GCC编译不过，也可能你们没有提供GCC的lib
