Custom Characteristic
I have the da14695 development kit pro and I have just ran a couple basic programs on it. I was wondering how I would go about creating a custom characteristic.
L2CAP bandwidth
Hello,
I'm still testing l2cap bandwidth with two usb dev kits(see my earlier post on Wed, 2020-01-01 16:24 ). I see certain patterns, which I can not explain.
How to do can change the remapp adress to 0x2002000?
I want to know how to manually OTA.
I did the following steps:
1. Write flash pxp_reporter.bin to 0x2000 and write new_pxp_reporter.bin to 0x2002000 by cli_programmer.
2. modify CACHE_FLASH_REG to 0x16102006(origin is 0x16009006) by Jlink("w4" command to modify it), and restart.
But it didn't work. The value of CACHE_FLASH_REG reset to 0x16009006.
How to do can change the remapp adress to 0x2002000? My goal is to switch images(active and upgrade image) in flash by modifying variables. How to do?
Thanks.
DA14695 Development Kit – USB resets after USB extracting
Hello Dialog,
I have combined two examples from SDK: PXP reporter and USB SMSD. I implemented a charging profile for my battery and connect the battery to J5 port. I have jumpers on J2(2:3) and J3(2:3). All works well, but when I insert/extract DevKit from USB port, DevKit reboots. Similar situation with powerbank( stucks at insertion/extraction). When I leave DevKit inserted and manually connect J2:2 and J2:3 all works well. What is may be wrong?
Thank you.
binary too big if emwin font is included
When using emWin library, if I use GUI_DispString() or other font-involved function, the binary size is easily overflowed and get the following errors.
ld.exe: xxxx.elf section `.text' will not fit in region `ROM' ld.exe: region `ROM' overflowed by 48864 bytesHow can I make font data not to use .text section?
Is there any guideline?
How to use emwin library properly
Hi, teams.
I have ported emWin library to my project, and create a new diplay driver for my board.
To test display, I copied very simple codes from examples like follows:
GUI_Init(); GUI_SetColor(GUI_WHITE); GUI_SetBkColor(GUI_BLACK); GUI_Clear(); GUI_FillCircle(40,40,40);GUI_Init() returns successfully, and screen_power_on(), screen_setup(), and screen_enable() functions are properly called.
But, GUI_Clear(), GUI_FillCircle() functions never works.
Unique Chip ID
Hi Dialog,
Is there any unique chip serial number, burned at the factory? I mean some number, like in the attachment. For my application is not possible to use BD address.

Hello!
I am a new user trying to familiarize myself with the SmartSnippets development environment. Im using:
Dev-kit:DA14695-00HQDEVKT-U
SDK:SDK_10.0.6.90
SmartSnippets:SmartSnippetsStudio2.0.10
How to use reboot_device.py
I have found "reboot_device.py" script in utilities/python_scripts/qspi folder.
ReadMe.MD file explains that this script can be used for resetting device, so I made the following launch script for external tools.
L2CAP bandwidth
Hello,
I put together a bandwidth measurement test using L2cap channel (credit based, etc).
I set PHY 2M, DLE 251 bytes, one central, one peripheral, one L2cap channel. I varied the connection interval and mtu size (up to 2500 bytes) but the maximum I get is around1Mbit/s. (with high mtu and 6 connection interval)
I was wondering if the current value I am getting is the maximum or is some of my settings off? Should I expect GAT services to be faster?
Thanks,
