Hardware Description
ASM11370 uses BLE to share button events to connected target, e.g.
ASM11374. Main system blocks:
• 3V CR2450 Cell Battery
• Microcontroller nRF52832 with ARM Cortex M4 CPU, 512kB flash and 64kB RAM
memory
•3 Buttons which individual status, e.g. press, release, etc, are exposed via BLE
• Communication during production test is done via Universal asynchronous
receiver
transmitter interface (UART)
• Programming is done via Serial Wire Debug Interface (SWD)
• Internal DC DC converter supplies microcontroller with 1.3 V to make it more
energy efficient
• RF Tuning at 50 Ohm before and after Bluetooth Band Pass filter that feeds the
signal into a 2.4 GHz Antenna
• The Antenna type is Bended monopole
• The Antenna Gain is 0.5dBi (includes a saw filter with 2dBi)

Software description
The software is written in C and based on Nordic
Semiconductor's Software Development Kit labeled nRF5 SDK
v15.3.0. The software consists of three parts:
• Bootloader used for upgrades
• Softdevice used for BLE radio parts
o the softdevice is not modified, it's provided as a binary
from chipset supplier Nordic Semiconductor
• Application used for the specific functionality.
When a connection is established via BLE to the ASM17360
unit, it routes push button presses via BLE. The source code,
SDK and scripts are stored in a Git repository.
