Battery service function in SDK5.0.3

Mon, 2019-06-17 16:16--Aaron Li

Hello Dialog Support team,

我正在通过SDK5.0.3和BLE_APP_PROFILE项目开发一个项目。当我的程序状态从连接转到断开连接时,为什么程序仍然可以运行batt_level_upd_cfm_handler()和app_bass_process_handler()函数?我的理解是,断开连接后应禁用所有电池服务程序。你能帮忙解释吗?多谢!

Best Regards,

How to wake up DA14850 from Sleep mode.

Mon, 2019-06-17 14:40--Gandhi

Hi,

我正在使用DA14850的商业委员会为我的项目。我正在研究SPS_DEVICE项目。

I have some questions for ble:

1. I am able to send data from serial terminal to DSPS Android App. Here I am typing some random data from keyboard and I see whole data displayed in DSPS app. Unfortunatly Im unable to do opposite. I would like to send data from app to serial terminal. I see there is an option to send the data in App. When I enter some data in send console of dsps app and click send I dont see any data at serial termianl. Is this possible?.

无法从闪存中读取/写入数据

Mon, 2019-06-17 07:50--Utkarash

Hello All,

I have used ble_peripheral example from the SDK 5.0.4 for refrence to build my application on daughter board of DA14583,

I use it Connection based method,

Where I get some data (I.e., 128 bytes) in connection based method and the same data I want to write/read to/from Flash.

I write data to flash when device disconnects from central, and similarly read data in periph_init function after all initilisation.

ALC DC offset calibration problem

Thu, 2019-06-13 17:45--yesways

We are using the ALC function of the DA7212 with success in several projects.

Recently we tried to use the automatic DC offset calibration, accessible through

the ALC_CTRL_1 register.

However, when we have completed this procedure, following the recommended

序列,ALC会奇怪:

- It will, as expected, lower the gain and thus the output volume when high sounds comes in

- It will NOT increase the gain again, unless there is SOME sound coming in.

If the input is quiet, the gain will stay low indefinetly.

error 125, AGDI: memory write failed

Hi ,

IM仍然是具有Keil和DA14580DEVKT-B SDK板的编程固件的新功能。

When i compile and debug previously , i have no problems running the sample code.

However after my Jlink firware upgrades , somehow when i debug, this error crop up :

*** error 125, line 10: AGDI: memory write failed (0x50000012)

以下是output of running debug in Keil.

SLG59M1736C stuck in "in-rush control" mode?

Wed, 2019-06-12 21:27--peter_ibeat

We have a design in production and we're observing a number of units with this IC exhibiting a strange behavior: The switch never fully closes and appears to remain in "in-rush control" mode, where the output voltage is at 1.86V instead of the 4+V at the input. All of our scope shots look clean: VIN is present before the ON pin is pulled up, and there are no glitches. The IC powers a circuit on an FPC with the load being the input of a boost converter, so there's about 10uF of capacitance there (nominally).

Oscillator pins conflict with DIP development board

Tue, 2019-06-11 14:51--dbvanhorn

In creating my first real application, I needed to use the on-chip crystal oscillator.

We have not been able to get the advanced dev system working yet, so I am using the DIP development board.

Parasitic loading from the DIP development board prevents the oscillator from running, so we cut off pins 16 and 17 on the OTP DIP board, so that the oscillator can run.

Cutting off those pins prevents the OTP from being programmed.

This is likely not a "bug" so much as "this is how it is", so I'm noting it for other users to be aware of.
