Capacitor Selection Criteria

Fri, 2018-05-18 06:36--electronherder

I am interested in using the DA9062 PMIC for a Zynq 7010 product. The data sheet has recommendations for capacitors, but I did not see much information about the requirements for them, such as min/max capacitance, package size, quantity, ESR, ESL, etc. The datasheet says"When selecting a capacitor, especially ones with high capacitance and small size, the DC bias characteristic has to be taken into account". I understand what DC bias is, so this suggests it is possible to use alternate components than those recommended.

Disable all interrupts

Thu, 2018-05-17 12:45--Ruchi Patel

Hello Dialog_Support Team,

My custom board has AC circuit part integrated and due to AC part after few minutes firmware hangs for no reason and device stops advertising. If i use same firmware with Discovery kit then it is working absolutely OK. I am using just one pin configured as output pin(PORT-2 PIN-1). I am not using any interrupt so there is any way to disable all hardware interrupts?

With Regards,

processing in user_app_system_powered stops advertisement

Wed, 2018-05-16 21:55--AnisM

I 'm testing the ble_app_sleep mode application, and I added a callback for theapp_on_system_powered
the call back just delays for 10ms to simulate processing and returns GOTO_SLEEP.

arch_main_loop_callback_ret_t user_app_system_powered(void)
{
delay_us(10000);
return GOTO_SLEEP;
}

when I press the button the device wakes up sends one advertisement packet and stops.
it is setup to advertise for 10 seconds with a 500ms interval.

How can I add device name in the iBeacon advertising data?

Wed, 2018-05-16 07:03--ustbzhangm

Hi,all.
I want to add device name in the advertising data.
As the maximal length of the advertising data is 0x1C (0x1F-3) bytes.
And the iBeacon data structure is:
uint8_t adv_header[2]; //static for ibeacon
uint8_t company_id[2];
uint8_t data_type; //static
uint8_t beacon_length;/ / static
uint8_t uuid[16]; //Configurable
uint8_t major[2]; //Configurable
uint8_t minor[2]; //Configurable
uint8_t tx_power;
The iBeacon structure occupy 0x1B (27) bytes.

DA14580通讯距离

结婚,2018-05-16 04:25--凌乱的爱

工程版本:5.0.4
使用工程为OTA工程加入扩展睡眠,因为低功耗的原因修改了广播间隔和连接间隔
广播间隔为500ms~1s
连接间隔450ms~500ms
连接间隔变长之后发现通讯距离缩短二分之一,以前可以到10m距离,现在距离缩短到5m以下
加了2.4G陶瓷天线发现也没什么大的变化,请问有什么办法可以在功耗不增加的情况下增加一点距离

APP crahsed when using timer0

Tue, 2018-05-15 00:34--sentimental

1Hello Dialog,
I have a problem with using timer0, and the app crashed every time. In my application, I'd like to use timer0 to sample sensor data repeatedly, say, every 2ms(500Hz), and then send data back to an Android phone. Previously I use app_easy_timer working well, but since the minimum time interval of the easy_timer is 10ms, I switch to timer0. I tested the timer0 sample project and seems working fine, so I modified the sample and added it into my code like:
