关于DA14580在mode_ext_sleep模式下运行情况
你好！
在mode_ext_sleep模式下，蓝牙还是能定时的唤醒，然后进行广播。如果我要在睡眠状态下蓝牙也休眠，然后通过外部中断唤醒，需要设置哪些地方？
Implementation of Button State Characteristic
Hello there.
I'm working on a project which main characteristic is the state change detection of a push button, quite simple.
I need to read the state of the button and send this value to the phone, so I 'll can know if the button has been pressed, which is exactly what the Button State Characteristic does.
对话培训材料展示如何使用控制点和LED状态特性实现自定义服务，所以我想知道是否有一个方法，但是使用按钮状态特征。
Thanks in advance
6.8V上VPP编程电压
Hello All,
I am looking to interface PAC1740 to MSP430 conroller. I am planning to connect the BLE in UART. I would like to flash the firmware to BLE through Jlink.
It is written in the design gide that we can flash the firmware to BLE through software debug pins however we can not debug. We can debug onlz when we used Jlink.
And also we need to input 6.8V to VPP is required. Is it comulsory to have 6.8V to VPP pin of BLE.
除了上面提到的情况外，我需要任何额外的电路吗？谢谢你。
通过自定义的通信协议修改mac地址后，无法进入低功耗
我正在尝试通过通信协议修改当前设备的mac地址，发现修改完mac地址后无法进入低功耗，具体方式是将自定义的数组拷贝进NVDS_TAG_BD_ADDRESS变量中，在测试蓝牙名称修改时，该方式确认可行，具体方式是写入NVDS_TAG_DEVICE_NAME中。（注：设备在此期间并未断电，而是通过goto语句进入了代码初始的地方重新对系统进行了初始化，因为并未使用flash），具体代码如下：
memcpy(nvds_data_storage.NVDS_TAG_BD_ADDRESS,device_addr,sizeof(device_addr));
进入低功耗代码：
app_default_sleep_mode = ARCH_EXT_SLEEP_ON;
arch_set_sleep_mode(app_default_sleep_mode);
user_scheduler_reinit();
ke_timer_set(APP_TIMER_API_MES1,TASK_APP,SECOND_TIME);
经经ke_timer并并启
Custom Notify value not send after BLE subscription
Hello,
I'm developing a project that transfers an accelerometer measurement via ble. I've successfully transferred them when they are only read characteristics and as a next step I want them to be notify so that you can get updates to your smartphone. I based it after the adc1 characteristic from the ble_perihperal example.
I first tried this with the first characteristic (the X-axis one) and once subscribed it loads one value and then never sends another again.
I used the light blue android app to check the characteristic.
Enabling CFG_TRNG error
I would like to enable the True Random Number Generator to create advertising intervals to prevent collision among several units.
I'm editing the DA1458x_beacon_v_5.40.2 project files.
在DA1458x_config_advanced.h我定义:
#define CFG_TRNG
Using Keil uVision v5.27.1.0 I click rebuild all target files. I then end up with this error:
.\out_580\dialog_beacon_580.axf: Error: L6218E: Undefined symbol trng_acquire (referred from arch_system.o).
At first the trng.h file gave me an error:error: unknown type name 'uint8_t'
DA7212 maximum input voltage at AUX inputs
Hi,
What is the maximum and minimum voltages the DA7212 can accept at the AUX inputs without (the risk of) damaging the IC?
在我们的电路中，VDD_A是1,8V。
Using GreenPAK without programming the NVM.
Forums:
Hi,
If I understand right, when using the GreenPack Deigner with the Developement board in emulation mode, the configuration I made is loaded into the chip in the socket into some RAM-like memory and the function that I want to test is realized by the chip in the socket. If I understand right again, the chip is programmed trough the I2C interface of it.
