firmware options

Single stack is a firmware providing only one protocol stack. However, all stacks are operated at the very same hardware.

Multi stack is a firmware providing a selection or all of the mentioned protocols, that might be switched during runtime.



The single stack requires less memory than the multi stack which leads to a cost reduction because of the ability to use an MCU with less memory, respective application software and pre-processing can be outsource to communication module. On the other hand, for the single stack switching the protocol is possible via bootloader / programmer only, whereas the multi stack is able to switch at anytime during operation.

A few feature highlights

quick start

... and easy onboarding using Command Line Interface (CLI) by STACKFORCE, available for Windows and Linux. Ideal for rapid-prototyping or usage of the radio module inside PC-based devices.

accelerated host development

... using "STACKFORCE API Transport Protocol" (SATP) via serial interface, either UART, I²C, SPI or similar. SATP also provides encryption and message authentication, for very sensitive applications.

Commercial Features

  • first level support
  • easy commissioning and configuration
  • warranty and maintenance
  • ensures a high quality product
