J-LInk Troubleshoot Document
Forums:
A new Jlink related document has been released (AN-B-052:DA1458x/68x Development Kit Jlink interface) regarding some malfunctions that have been observed with dialog's development kits due to the automated update procedure of the Jlink driver. The document is located under the 58x/68x application notes pages.

DA14683 Power Supply
Hi,
We have built boards based on DA14683 chip. The boards are yet to be programmed.
I see that there is no voltage seen on "VDD1V8P" rail on some boards, on a very few boards it is about 2.6V and on most of the boards, it is 1.8V. Rest of the supplies V33, VDD1V8, V12, V14 are measuring accurate on all boards. We have 2 sensor chips and 1 RTC chip on the VDD1V8P rail.
The board hardly draws any current. Can I know what is happening to this rail? How to fix it?
Regards,
Vijay
How to adjust the Bluetooth transmit output power
Hi
I use DA14682 chip，and i use DA1468x_DSPS_v_1.160.2 SDK
help me please~
The document（DA14682_BA_FS.book） is say : 0 dBm transmit output power and -94 dBm receiver sensitivity (BLE)
How do I set the Bluetooth transmit power in the program?
I didn't find any function in the SDK to set the transmit output power.
I want to increase the Bluetooth transmit power to use it at a greater distance.
Securing SUOTA
Hi,
Using the example provided by DS allows any user to approach our device and upload new user firmware. Is there an easy way to secure against this? A way to enable or disable the service? Or maybe only allow it under certain conditions?
Thanks in advance.
Number of services in BLE
Hi dialog
I am working on a custom board based on DA14681, and in firmware i am using around 7-8 services. They are working fine. I want to add 5 more services. Is there any limit for number of services? If yes then how many? And do they affect performace of overall setup?
Thanks
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

How to reboot/reset DA14681 from firmwrare.
Hi dialog,
I am working on my custom board based on DA14681 and it is working fine. In firmware i want to make a logic to restart the 681 as it restarts when the reset button is hit.
So is there any software command that will reset it?
Thanks
LED continuous glow
Dear Dialog team,
Thank you for your support.
We have custom board made from DA14683. We have 3 LEDs on this board and they are not tied to any GPIOs. We use LED low level driver APIs turn on them. Below is the reference code:
