Hello,
we have developed a custom Board with a DA14680. After some tries we could flash it successfully by using the JTAG from the
Basic Development KIt. However I wanted to flash a new Program and it doesn't work I always get the error cannot connect to gdb.
I am using SDK 1.0.8 and I flashed it in Smartsnippets studio with program_qspi_jtag_win.
Dear Dialog,
I follow the instructions of UM-B-056 section 5 build the proximity reporter project. and I successfully programming it in da14681 pro board with 14681ae-atdb daughter board.

Hello,
I'm working on adding support for the flash device we are using, as it is not one of the few supported by default. I have a few questions so I can better understand the mode the flash should be operating in:
- Are any of the non-volatile registers set/configured in the W25Q80EW flash on the pro DK?
- Is 'performance mode' the same as XIP (execute in place)?
We are developing a product using the DA14680 and are hoping to use the built-in flash to boot from and store some data. We have our code working on the DA14681 basic dev kit and now our custom prototype boards based on DA14680 we need to get it working on that platform
I can connect to the DA14680 on our custom board with a J-Link via SWD and can also talk via UART at boot time.
请问：
我的使用情况：
硬件： 测试io(p3_5)外接led,外挂eeprom芯片到i2c2(p4_0,p4_1)
软件：
1.配置uart作为调试使用
2.官方pxp_reporter工程，pxp任务正常打开，同时新建 一个1s周期test任务，执行io翻转，代码正常运行.
3.官方pxp_reporter工程，屏蔽掉pxp任务，同时在test任务下新增初始化i2c2，写eeprom地址0x00，数据：0x51，周期读取地址0x00，数据等于0x51，代码正常运行.

Hi Dialog,
I develop a custom application (peripheral role, GATT server).
The application receives a BLE_EVT_GATTC_MTU_CHANGED event even though application doesn't trigger ble_gattc_exchange_mtu(). For what reason?
Does the event occur when MTU exchange is triggered by peer device? Unfortunately I don't know the exact behaviour of peer device.
Thanks

Hi Dialog,
We developed a dev board of minimum DA14681 system, based on BASIC DevKit.
The code we run correctly on BASIC Dev kit, it just simply print "hello world" to COM port periodically.
But when I downloaded the image to own designed board, the code only run for a short time, after 10 seconds, the program halted. We built 5 dev boards, all show the same error.
SDK1.0.8 is now released....
- Integration of SEGGER USB library with CDC and MSD Support
- Integration of State-of-Charge API
- 4.2 Secure Connections support at the BLE Framework Level
- Security Toolbox that makes use of ECC and Hash Blocks of the Device
- Modified flash driver architecture for support of different QSPI flash types
- Restructured configuration parameters for power and peripheral management
Hi there,
Today we received the DA14681 Development Kit - Pro and the DA14681 HomeKit Development Kit.
However, when we try to access the Videos section [1] we get a "not authorized" error. Trying to download the SDK [2] are asked to accept the license agreement, however, the web page does not have any checkbox at all.
Please help as we do have to kick off our evaluation.
Thanks,

Dear Sir,
I run the Multi-link demo and add below timer trigger every 1 sec after connected to the mobile phone. However I receive wrong RSSI value every 20~30 seconds. May I know how to avoid this? Thanks.
rssi_tim = OS_TIMER_CREATE("rssi", OS_MS_2_TICKS(1000), true, (void *) OS_GET_CURRENT_TASK(), rssi_tim_cb);
static void rssi_tim_cb(OS_TIMER timer)
{
printf("rssi_tim_cb\r\n");
OS_TASK task = (OS_TASK) OS_TIMER_GET_TIMER_ID(timer);
OS_TASK_NOTIFY(task, RSSI_TMO_NOTIF, OS_NOTIFY_SET_BITS);
}
