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

  1. Go to https://os.mbed.com/teams/Sigma-Delta-Technologies/, and find SDT51822B on the right column. /media/uploads/jwyune/screen_shot_2018-10-13_at_5.36.27_pm.png
  2. "Add it to your Mbed Compiler" by clicking it on the right side. /media/uploads/jwyune/screen_shot_2018-10-13_at_5.41.47_pm.png /media/uploads/jwyune/screen_shot_2018-10-13_at_5.42.27_pm.png

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.

  1. Go to https://www.sigma-delta.tech/in11. /media/uploads/jwyune/screen_shot_2018-10-13_at_5.53.53_pm.png
  2. You can find its interface firmware at the bottom of the page. Save it on your computer. /media/uploads/jwyune/screen_shot_2018-10-13_at_5.54.30_pm.png
  3. Now, connect IN11 to your computer, while the RST button is held down. /media/uploads/jwyune/screen_shot_2018-10-13_at_5.59.30_pm.png
  4. You will see a new disk volume appear as \CRP DISABLD. /media/uploads/jwyune/screen_shot_2018-10-13_at_5.56.46_pm.png
  5. 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
