SmartBond™ DA14682 and DA14683
Single-chip high-security Bluetooth 5 solution with expandable memory
The SmartBond DA14682 and DA14683 are the world’s first single-chip solutions for Smart Home, Industrial and wearable devices that meets the highest security standards. These highly integrated System-on-Chip (SoC) devices support Bluetooth 5 as well as Bluetooth mesh, and include a range of dedicated features to ensure cutting-edge security for both consumers and developers.
As part of our SmartBond range, both SoCs offer industry-leading performance from the lowest power consumption and smallest footprint. Their flexible architecture ensures plenty of processing capacity when you need it while saving power when you don’t. It also allows the devices to manage multi-sensor arrays and enables always-on sensing.
Both devices offer extensive memory capacity and differ only in their memory configuration. Specifically, the DA14683 supports unlimited external Flash for maximum design flexibility while the DA14682 includes 8 Mbits of onboard Flash, making it ideal for applications with tight space constraints. Both options allow you to benefit from over-the-air updates.
To further simplify your development, our SmartSnippets™ software and versatile Hardware Development Kits help you optimize your software for power consumption.

SUOTA not working after editing partition table (DA14680)
Posted by alarner 15 points 3 repliesHello,
I adjusted the partition table in order to optimize space. Everything worked just fine, except when I try to update the firmware via SUOTA it no longer works. I am able to upload the new image but when the chip reboots it is still back on the old version. Do I need to edit any other files? I have just changed bsp/config/1M/suota/partition_table.h to look like this:
PARTITION2( 0x000000 , 0x01E000 , NVMS_FIRMWARE_PART , 0 )
PARTITION2( 0x01E000 , 0x001000 , NVMS_PRODUCT_HEADER_PART , 0 )
PARTITION2( 0x01F000 , 0x001000 , NVMS_IMAGE_HEADER_PART , 0 )
PARTITION2( 0x020000 , 0x02B000 , NVMS_FW_EXEC_PART , 0 )
PARTITION2( 0x04B000 , 0x02C000 , NVMS_FW_UPDATE_PART , 0 )
PARTITION2( 0x07D000 , 0x002000 , NVMS_PLATFORM_PARAMS_PART , PARTITION_FLAG_READ_ONLY )
PARTITION2( 0x07F000 , 0x001000 , NVMS_PARTITION_TABLE , PARTITION_FLAG_READ_ONLY )
PARTITION2( 0x080000 , 0x006000 , NVMS_PARAM_PART , 0 )
PARTITION2( 0x086000 , 0x07A000 , NVMS_GENERIC_PART , PARTITION_FLAG_VES )

It was working with the default 1M SUOTA partition table but not with the modified one. Thanks

Hi Aarom,
The partition table seems OK. Did you also change the partitioning in the ble_suota_loader? If not, please use the same partitioning.
Please erase the flash using the python scripts to ensure the correct partition table is used.
Since you are using a custom partition table, I would recommend following the above tutorial : http://lpccs-docs.dialog-semiconductor.com/da1468x_adapters_concept/nvm…
Additionally, please also check section 9.1.4 SUOTA Flash memory layout from the um-b-056 user manual : https://www.dialog-semiconductor.com/sites/default/files/um-b-056-da146…

Hi Aaron ,
Thanks for your question online.
Question for better understanding: Is it working with the default 1M SUOTA partition table? Or it is not working with the modified partition scheme?
Thanks, PM_Dialog
