DA14531 SmartBond TINY Module

Unable to program the Flash in the module

Thu, 2020-10-29 14:42 -- ngml73


I have just bought a new DA14531MOD-00EVKT-P and setting up according to session 5.9.2 of  'um-b-141_da14531_smartbond_tinytm_module_development_kit_hardware_user_manual_1.1.pdf'

I used Flash programmer v1.0.4.2972 to erase and program 'codeless_531_standalone_set_two.hex' and other hex file and the same error found. 

Attached is the log file. 

Please advise if I missed any steps


Programming custom DA14531 Module over 1 wire UART

Fri, 2020-10-23 00:43 -- AdamShier



I have 2 questions.


1) I have 1 wire uart programming connected in the following setup. A ftdi cable (TTL-232R-3V3 cable) with rx and tx connected with a 1k resistor, with that connected to p05. The ground of the uart cable is connected to ground of the board. The board is powered by batteries, 3V. When I go to program it in the smart toolbox, it always just responds 

         Error while waiting to receive STX from FTDI device.  

any thoughts on why that might be? 


DA14531 BLE Detected issue

Mon, 2020-10-19 05:40 -- pooja

Hi PM_Dialog,

    In my custom board used DA14531 Module.

    Programmed DA14531 Module using  "codeless_531_set_two_standalone" which is available in DA145xx_CODELESS_6.380.12.6 .  

    Downloaded "Smart console"  app from play store.

   open the smart console app in android and the DA14531 Module detected in mobile.

   Here comes the main issue,

             1.In the app it detects the module but unable to connect module.(Its shown message like disconnected while trying to connect the module)

Sleep - Wake up - Sleep

Sat, 2020-10-17 21:43 -- harry84

I m working on DA14531. How the SoC go into extended or deep sleep mode and how to set a timer to wake up it automatically.
Actually, I need that device automatically wakes up after every minute and reads data from a GPIO and then writes them to RAM and finally go back to sleep mode.

Is there any example code for this kind of scenario?

It should be mention that the device must sent the saved data to another device through BLE connection every day.


Thanks in advance

DA14531 Digital Logic Level

Wed, 2020-10-14 21:08 -- magergar

What is the logic level for the module DA14531 ?
More specifically what is the voltage that the module detect for a 1  on the GPIO?

I'm asking this because  I want to use an I2C isolator  but this kind of device has a voltage reference (around 0.6V) on one side so it doesn't create an infinite loop
and I'm able send data but can't recieve, and looking at the osciloscope  I found that a signal that is not completely driven to ground (an acknoledge bit send by the slave) is not recognize by the module, and I could not find anything in the datasheet.

Read ADC1 Value in ble_app_peripheral example

Wed, 2020-10-14 20:57 -- jwpearce

Please help me understand how to communicate characteristic values using READ as opposed to NOTIFY.  For example, in  ble_app_peripheral the NOTIFY message starts a callback timer that makes the measurements and sends the results into the database.  I cannot find where simple READs get handled.  Please show me code where a characteristic value is accesed using a READ message.

Thank you.

Dear Dialog Team

I am working on an application to communicate in between DA14531 SmartBond TINY Module and u-blox BLE module, I am successfully connecting and data transferring in between them. (In DA14531[peripheral mode] I am using OpenCPU mode and in u-blox BLE[central mode] module I am using AT Mode)
