I'm using ble_examples\ble_app_peripheral project of the SDK
I treid via sending the GATTM_ADD_SVC_REQ message to add a new service, as follows :
step0 struct gattm_add_svc_req * req = KE_MSG_ALLOC(GATTM_ADD_SVC_REQ,TASK_ATTM,TASK_APP,gattm_add_svc_req); req-> task_id = TASK_APP; req-> total_size = 36; // 16 + 19 +1 req-> nb_att_uuid_16 = 2; req-> nb_att_uuid_32 = 0; req-> nb_att_uuid_128 = 1; req->start_hdl=0; ke_msg_send(req);I'm working in sdk 5.0.4
I want to change the exist service uuid and attribute uuid at runtime, because the attribute uuid is configured by the customer at run time through the serial port
I'm developing an AT instruction bluetooth module
I'm doing the following
Hi,
I'm trying to make SEGGER RTT work. I'm using CMake to compile my application on Ubuntu.
I added `#include SEGGER_RTT.h` to `main.c`. In main() I call `SEGGER_RTT_Init()` and then I just do a while loop with `SEGGER_RTT_WriteString(0, "HELLO \n");`
In my `custom_config_qspi.h` I added `#define CONFIG_RTT 1`.
I also added the SEGGER_RTT.c and SEGGER_RTT_printf.c and SEGGER headers.
This is what I do:
- Build and flash my DA14681 microcontroller
- Grep from memory map the address of _SEGGER_RTT
您好，
我参照DA14580_KEYBOARD_3.10.2例程修改的HID-Keyboard从机例程，发现市面上的蓝牙适配器搜不到我的设备，但是我的keyboard可以被手机，平板，笔记本都能搜到，且连接成功，使用正常。起初我以为是广播包这边问题，但我无论怎么调整，蓝牙适配器就是搜不到。蓝牙适配器应该是好的，它能成功搜到手机，蓝牙耳机等其他蓝牙设备。就有几点比较疑惑：
1.因为手机能被蓝牙适配器搜到，就想参照下手机广播跟我的keyboard广播有什么区别，好进行修改。就尝试用抓包软件去抓手机广播进行分析，结果发现抓包软件好像抓不到手机广播，好像蓝牙耳机的广播也抓不到，这原因是什么？
2.我的keyboard需要怎么修改，才能让蓝牙适配器搜索到？
Hi,
How do I get a toolchain for the DA14195/14495?
We've got a DA14495 Eval Kit which contains a sheet of paper saying to visit your support website to access app notes, tools and software. So I'm here, but can't find tools or datasheets.
Please can you point me at them
Dear
I would like to know if it is possible to generate current source from greenpack in this device. Thanks

I am designing a circuit board that uses a DA9063 PMIC. In the past I used this part and a custom part was developed per our board requirements.
I had a few questions about programming:
The DA9063 documentation I have read indicates the following programming methods:
1. Evaluation kit:(for small prototype qty)
2. In Circuit Programming Volume < 30K
3. Custom Programmingfrom Dialog > 30K
Want to initially program a few blank parts using an evaluation board and socket daughter card
I am trying to apply the patch provided for the Sweyntooth vulnerability. The device is DA14580. There is some discrepancy in the install.txt. The expected log output states
"patching file dk_apps/src/plf/refip/src/arch/main/ble/arch_main.c"
but the diff tries to patch a different file in "sdk/platform/arch/main/arch_system.c"
I would like to seek your opinion
Our product has to comply the BSI standard, there are two high risk non-conformities related to bluetooth issue
The current IC we used is DA14580 sdk revision number v_5.150.2, Could you advise how to modify the SDK configuration to meet the requirement showed above?
Our project timeline is incredible tight, we are eager to get your response ASAP. Much appreciated!
Dear
I am using PGA in SLG46620V and I dont know it is not possible configurations to use the channel 2, I mean, it is possible configurate PGA as Differential single or pseudodifferetntial, but in any mode it is not possible use IN+Channel2
Thank you
regards
