14. Custom ﬁrmware

14.1. Custom conﬁguration of standard ﬁrmware

The conﬁguration of 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 with a unique ordering number for a speciﬁc customer that needs this

conﬁguration.

For example if the UART baud rate shall be changed from the default value to another value.

This variant will result in a customer exclusive module with a unique ordering number. This

will also ﬁx 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

customer release procedure.

14.2. 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

customer 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

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.

14.3. 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.
