6.2 BMDware Pin Functions
Rigado BMDware is programmed on the BMD-300 Series at the factory. BMDware provides UART-to-BLE Bridge,
beaconing, and Direct Test Mode (DTM) functionality. The pins in Table 5 below describe the pin functionality in
BMDware. DTM Mode, Beacon-Only Mode, and AT Command Mode pin states are checked at BMDware start-up
to configure BMDware as required by the user, and are then set to Hi-Z to conserve power. For further details on
BMDware operation, please see the BMDware Datasheet that can be found at
beaconing, and Direct Test Mode (DTM) functionality. The pins in Table 5 below describe the pin functionality in
BMDware. DTM Mode, Beacon-Only Mode, and AT Command Mode pin states are checked at BMDware start-up
to configure BMDware as required by the user, and are then set to Hi-Z to conserve power. For further details on
BMDware operation, please see the BMDware Datasheet that can be found at
. BMDware can be
overwritten by RigDFU with custom application firmware, or removed along with RigDFU by a full chip erase.
