在使用SDK5.0.4里面sleepmode例程过程中，我发现在蓝牙连接前的广播阶段，程序会不断的调用BLE_WAKEUP_LP_Handler(void)，每次调用就会调用periph_init()函数。现请问：
1、BLE_WAKEUP_LP_Handler(void)在什么情况下会触发，调用它的时间间隔在哪设定。
2、我的程序设计了一个外部按键中断，初始化是在periph_init()里面，但是发现蓝牙没有连接的时候中断还起作用，连接后中断无法进入。不知道是在哪里把中断禁止了。
3、我想实现按键中断后能够主动进入休眠模式，是不是直接调用arch_goto_sleep（）函数。
4、还有就是在使用GPIO中断时，初始化完就会直接进入中断，不知为何。
Hi there,
I am working on the design with DA9063.
For the backup battery VBBAT pin, can I connect it an always on power supply 3.3V instead of a real coin battery?
And I'd like to keep 32K_OUT being always alive even the VSYS is off.
Is that workable? Thanks!
I use DSPS host project to make a scanner. But,I can't get a full packet in .
我有一个外围设备与27个字节长Packet. But, every time it goes to , I got 18 bytes data. Device name was cut off.
Here's the data I captured from BLE Tools:
02 01 06 07 03 0F 18 0A 18 D0 ED 13 09 45 44 44 30 31 32 33 34 35 36 37 38 39 41 42 43 44 45 --- 08 FF 44 4C 54 20 50 3A 4E
And what I get form param->report.data:
02 01 06 07 03 0F 18 0A 18 D0 ED 13 09 45 44 44 30 08
How do I get the full packet like BLE Tools get?
Thanks!
Hi,
I am using the SPS Host example code for scanning.
Can you help me understand the interval settings in "static const struct scan_configuration user_scan_conf".
What I am looking for is that the Device needs to scan for BLE Beacon devices for 100ms in every 2 seconds interval.
How do i go about setting this.
I know that waking up from Deep-Sleep takes more time than waking up from Extended Sleep.
How much is it in units of uA*s ?
Advertising very fast is more power-efficient using Ext-Sleep, and advertising very slow is more power-efficient using Deep-Sleep.
I am trying to calculate the point of balance - at which advertising frequency the total power consumption using Ext-Sleep equals to the total power consumption using Deep-Sleep.

Hi.
Hello,
I was trying to program my custom board using Jlink Ultra+ and i got the following error:
Hi
I'm working on a DA9063 Design with an additional external 3.3V Converter.
I added a attachment with a simplified Power Tree and Timing Diagram.
The external 3.3V DC/DC Converter has an Enable and a Power Good Signal.
I want that the DA9063 enables after Startup the 3.3V Enable Signal and waits until the 3.3V PG Signal is given.
After that the DA9063 should start with his own Power Sequencing.
Dear Dialog Semi,
we use nRESET, nIRQ on VDD_IO1 with 1.8V to drive a CPU input. The signals are configured for open drain operation with a pull up to 3.3V (CPU side). From the datasheet, table 4.4 I read that the maximum allowed voltage in open drain mode is VDDREF. In our case this is 5V (Vsys).
Can you confirm the 3.3V pull up is within specification for the two signals.
Best regards
-Rene
Gentleman,
is there a standard/preferred connection for DA9063 in circuit programming. When using the eval board the connection will have to be made by a special cable. I wonder what the interface is when using the programming kit "DA9061_2_3 ICP KIT" mentioned in app note AN-PM-080 "In-Circuit Programming of DA9061/2/3".
In other words: Is there a documentation for "DA9061_2_3 ICP KIT"
Best regards
-Rene
