More info please visit https://www.nordicsemi.com/Software-and-
Tools/Development-Tools 2.3 Protocols This module support Bluetooth 5, Bluetooth Low Energy,Bluetooth mesh,Thread,802.15.4,ANT, 2.4GHz proprietary. So we can use different protocols for different situations. Software Development Kit Nordic Semiconductor's Software Development Kits (SDK) are your starting point for software development on the nRF51 and nRF52 Series. It contains source code libraries and example applications covering wireless functions, libraries for all peripherals, bootloaders, wired and OTA FW upgrades, RTOS examples, serialization libraries. More info please visit https://www.nordicsemi.com/Software-and-Tools/Software/nRF5-SDK You can also download the SDK for coding development . 2.4 SoftDevices Nordic Semiconductor protocol stacks are known as SoftDevices. SoftDevices are pre-
compiled, pre-linked binary files. SoftDevices can be programmed in nRF5 series devices, and are freely downloadable from the Nordic website. Please download that here:
https://www.nordicsemi.com/Software-and-Tools/Software/S132 Over-The-Air DFU The SoC is supported by an Over-The-Air Device Firmware Upgrade (OTA DFU) feature. This allows for in the field updates of application software and SoftDevice. 6 Shenzhen Holyiot Technology Co.,Ltd www.holyiot.com info@holyiot.com 3.

Mounting our board on the host PCBA We suggest that you mount our RF board(HOLYIOT-21033 -nRF52832) on the board like that:
1. For the best Bluetooth performance, the antenna of the area need to extend about several mm without ground under the antenna of the edge of the host PCB. 2. The second choice is that place our board at the corner of host PCB, the antenna of board need to extend several mm outside of the Ground plane of the host PCB. 10 Shenzhen Holyiot Technology Co.,Ltd www.holyiot.com info@holyiot.com 5. Miscellaneous Soldering Temperature-Time Profile for Re-Flow Soldering. Maximum number of cycles for re-
flow is 2. No opposite side re-flow is allowed due to module weight. 11 Shenzhen Holyiot Technology Co.,Ltd www.holyiot.com info@holyiot.com 6.
