13. Custom firmware
13.1. Custom configuration of standard firmware
The configuration of the standard firmware includes adoption of the non-volatile Usersettings
(see chapter
) to customer requirements and creating a customized product on base of the
standard product.
This variant will result in a customer exclusive module with a unique ordering number. It will
also freeze the firmware version to a specific and customer tested version and thus results
in a customer exclusive module with a unique ordering number.
Further scheduled firmware updates of the standard firmware will not be applied to this
variant automatically. Applying updates or further functions require a customer request and
release procedure.
13.2. Customer specific firmware
A customer specific firmware may include "Custom configuration of standard firmware" plus
additional options or functions and tasks that are customer specific and not part of the stan-
dard firmware.
Further scheduled firmware updates of the standard firmware will not be applied to this vari-
ant automatically. Applying updates or further functions require a customer request and
release procedure.
This also results in a customer exclusive module with a unique ordering number.
An example for this level of customization are functions like host-less operation where the
module will perform data generation (e.g. by reading a SPI or I
2
C sensor) and cyclic trans-
mission of this data to a data collector, while sleeping or being passive most of the time.
Also replacing UART with SPI as host communication interface is classified such a custom
specific option.
Certification critical changes need to be re-evaluated by an external qualified measurement
laboratory. These critical changes may occur when e.g. changing radio parameters, the
channel access method, the duty-cycle or in case of various other functions and options
possibly used or changed by a customer specific firmware.
13.3. Customer firmware
A customer firmware is a firmware written and tested by the customer himself or a 3rd party
as a customer representative specifically for the hardware platform provided by a module.
This customer firmware (e.g. in form of a Intel hex file) will be implemented into the module’s
production process at our production side.
This also results in a customer exclusive module with a unique ordering number.
The additional information needed for this type of customer firmware, such as hardware
specific details and details towards the development of such firmware are not available for
the public and can only be made available to qualified customers.
