Multiple connections

Sun, 2020-07-26 15:29 -- BenjaminDu

Hi dialog,


I want to have 1 master connectted to several other slaves,but I found there is little introduction.

I have the following question hope you can help.

1. I'm now using DSPS demo, is it possible for me to change it into a 1 to muti( eg. 6)  connections? any modification needed?

2. The speed may be lower than  one to one connection, can you tell me the speed of 1 to multi connections? may be 1/10 of that of one to one?

3. Is one to muti connection as stable as one to one ? or there is possibility one to muti is not as stable?


Ethernet Module

We are designing a project where many sensors will be integrated to peripheral devices, then the peripherals will be connected central devices every 15 minutes. We will connect the central devices to main server with ethernet modules using spi. How does that sound, is it implementable ? 

Peripheral Device(DA14586)--> BLE --> Central Device(DA14586, Tcp Client) --> Ethernet Module(ENC28J60 etc.) --> Main Server

Especially, we have anxiety about tcp clients on central device side, thanks for suggestions.

OTP failed clearing memory address

Wed, 2020-07-22 23:52 -- dbonelli


I am attempting to OTP burn a DA14585 microcontroller on a custom PCB using a development kit pro. I was able to connect to and read my board successfully, but the OTP burn failed. The message I recieved said, "Failed clearing memory address 7FC7C08." I will include the full log at the bottom of this message.

In my Memory Contents table, I am only able to view memory addresses 0x07F80000 to 0x07F8FFF8. I have no idea what is going on at address "7FC7C08." Do you have any suggestions as to how to proceed?

Thank you.

How to use UART reception in broadcasting

Wed, 2020-07-22 08:05 -- 孙梦君


   How to use UART reception in broadcasting and why to use UART reception in broadcasting will cause the error of MOVs R0 R0.

   The occurrence of this problem is caused by calling the uart_receive () function in broadcasting.

   Is it caused by sleep in the broadcast gap?


Thank you very much.

Recommended method for OTP

Tue, 2020-07-21 18:23 -- dbonelli


What is the best method for OTP burning a DA14585 on a custom PCB? It is my understanding that a custom PCB can be programmed via jumper cables from a development kit, but I would like to know how Dialog Semiconductor recommends OTP burning a DA14585. For instance, should a manufacturer strictly handle OTP, should the microcontroller be OTP by a separate device and then soldered to a custom PCB, etc.?
