  • Page 37: Using The 2 Mbit Phy

    2 MBit. To switch the phy after the connection has been setup the Proteus-e offers the command CMD_PHYUPDATE_REQ . As response to this request a CMD_ PHYUPDATE_IND is returned from the Proteus-e, that gives feedback if the connection was switched to the new phy, or if the connection partner rejected the request.

    UART may detect a 0x00-byte with frame error. To guarantee a clean UART communication, the host controller may not accept bytes with frame errors and flush its RX buffer, after pulling the module’s /RESET pin LOW.

    • Cleaning processes using alcohol or other organic solvents may draw solder flux residues into the housing, which won’t be detected in a post-wash inspection. The solvent may also destroy the label and ink-jet printed text on it. Proteus-e reference manual version 0.3 © November 2021 www.we-online.com/wireless-connectivity...

  • Page 154: Physical Specifications

    Table 29: Weight 19.3. Light sensitivity Inside the Proteus-e a light sensitive WLCSP package is used. This package is sensitive to visible and near infrared light. As the chip is not completely shielded on the sides, any mounting without enclosure could lead to malfunction. This should be taken into account when designing an enclosure for the end device.

    R&TTE directive 1999/5/EC and the RED directive 2014/53/EU of the European Union (EU). The Proteus-e can be operated without notification and free of charge in the area of the Eu- ropean Union. However, according to the R&TTE / RED directive, restrictions (e.g. in terms of duty cycle or maximum allowed RF power) may apply.

  • Page 164: Oem Requirements

    The OEM must ensure that the following conditions are met. • The Proteus-e will be used at a distance of at least 10 mm. • End users of products, which contain the module, must not have the ability to alter the firmware that governs the operation of the module.

  • Page 165: Change In Id / Multiple Listing

    Since the firmware application created by integrators of the Proteus-e cannot be controlled by Würth Elektronik eiSos, the module integrator will have to take over this responsibility. This process is called "change in ID" for FCC and "multiple listing"...
