Introduction
Introduction¶
SDT51822B is a Bluetooth Low Energy (BLE) 4.0 board with Nordic Semiconductor's nRF51822. This project demonstrates BLE serial communication between the board and a smartphone. We hope this page gives you a better understanding on Sigma Delta Technologies' (SDT's) hardware platform.
Add SDT51822B to your Online Compiler¶
- Go to https://os.mbed.com/teams/Sigma-Delta-Technologies/, and find SDT51822B on the right column.
- "Add it to your Mbed Compiler" by clicking it on the right side.
Update DAPLink firmware on IN11¶
In order to program and debug a SDT board, you need to update interface firmware. For SDT51822B, we use IN11 and the corresponding interface firmware.
- Go to https://www.sigma-delta.tech/in11.
- You can find its interface firmware at the bottom of the page. Save it on your computer.
- Now, connect IN11 to your computer, while the RST button is held down.
- You will see a new disk volume appear as \CRP DISABLD.
- Replace firmware.bin with the downloaded firmware, and power cycle IN11.
- On Windows, simple drag-and-drop works.
- On Linux/Mac, use command: dd if={new_firmware.bin} of={firmware.bin} conv=notrunc
