Introduction

The BM70/71 memory programming user’s guide provides information about programming the memory configuration parameters of the BM70/71 Bluetooth® Low Energy module (BM70/71 module). To meet the wide array of requirements in the Internet of Things (IoT) application space, the design of the BM70/71 module allows customizing the behavior of the internal Bluetooth stack operation and the hardware peripheral operations. The configuration parameters allow the designer to understand the customizable behavior of the BM70/71 module. These configuration parameters are available in the internal programmable Flash, which are erasable, readable and writable.

Microchip provides two Graphical User Interface (GUI)-based PC tools for programming the memory, such as:
  • User Interface tool (UI tool) – For reading or modifying the configuration parameters to change the BM70/71 module behavior
  • Flash update tool (isUpdate tool) – For changing the firmware version on the BM70/71 module. There are certain cases where using these PC tools is not optimal.
Note: The designer must not use the PC tool provided by Microchip to program the configuration parameters or perform a firmware update.
