DA14681 sleep and wakeup timer mode?

Wed, 2020-09-23 10:48 -- mahmed106

Hi dialog

I m working on custom baord based on DA14681. I want to know how to go into sleep mode and how to set a synchronous timer to wakeup automatically.

Actually my application needs that device automatically wakesup after every minute, read ADC temperature, writes to flash and go back to sleep. I want to know is there any example code where this kind of sleep is implemented. Or if you can help me for this?

Secondly device must also be availble for SUOTA update or BLE data transfer. Please tell how that can be managed while sleeping?

DA14681 goes into hibernation but after 2 wakeups it do not go again?

Hi dialog

I am working on custom board based on DA1468x i am using command                                        

pm_resume_sleep();
pm_set_sleep_mode(pm_mode_hibernation);

to put it in hibernation. It goes into hiberanation and wakeups with external GPIO interrupt but after waking up 2 times it do not go into hibernation.

Is it related to that logic that hibernation mode is for ship devices to customer . When customer on the device then this piecce of code is disabled?

Is my understanding right?

How can we send negative value via BLE?

Hi dialog

I am working on custom board based on DA14681 and sdk is 1.0.14.1081.
In file ble_gatts.c all functions are taking input as uint16_t .
My questions is if i want to send data of negative value like int8 or int16. How can i send that? Because ble_gatts.c is an sdk file which i dont want to change.

Thanks

 

Here is the all file

DA14681 power consumption is high

Fri, 2019-06-21 11:50 -- song

Hi,

My PCB USES DA14681 and other peripheral chips, which are powered by GPIO of DA14681.

When DA14681 is in extended sleep mode, GPIO power is turned off, and the battery output current is 102uA. In DA14681 hibernation mode, the battery output current is 1.4uA.

Some PCB extended sleep power is abnormal, battery output current is 1.9mA, but hibernation power is normal.

I wonder if the power anomaly might be related to DA14681.

Bonded information location

Wed, 2019-02-06 20:25 -- Jitendraprasad

Hello Dialog team

I am working on DA14681 MCU. My application is to store one bonded information (Peer device MAC address). And also store sensors data using using "ad_nvms_write" API. I used ad_nvms_open( NVMS_GENERIC_PART ). "NVMS_GENERIC_PART " partition for data storage.
Now problem is, device can bond the peer device successfully and store the information and I can get the bonded information after each power cycle. But if I write the sensors data samples bonded information erased/overwrite (?).

Unable to debug the code into device DA14681-01

Hi!

I am using device DA14681-01 for my research work. we have purchased DA14681 for creating a prototype. However, I am facing a problem while loading the code into the chip. Initially, I started with the basic code to blink the D2 led. but I am getting the following error. I have tried to find this error on your forum but could not get any answers.

Please help me out, Thanks in advance. Follow below for the error.

da14681自定义充电电池配置

Wed, 2019-01-23 07:10 -- Linchaoran

你好,请问下关于充电电池的几个问题:
1、pxp例子里关于充电电池配置文件custom_socf_battery_profile.h文件内的vol_chg_0_0 = 3067; //120mA charging,这个值是怎么算出来的,有公式吗,看了UM-B-075_DA1468x_State_of_Charge_Functionality_v1.2_0.pdf文档,需要一个硬件设备连接后才能使用,目前没有这个设备;
2、dg_configBATTERY_CHARGE_VOLTAGE和dg_configBATTERY_TYPE_CUSTOM_ADC_VOLTAGE 这两个有什么区别?
3、vol_dis_low_0和vol_dis_high_0 必须通过UM-B-075这个文档中应用程序测出吗,有其它方式吗?
