WIRELESS CONNECTIVITY & SENSORS
User manual Proteus-III
• Connect the WAKE_UP pin to the host controller to leave power saving modes, like
the sleep mode.
• Connect the BOOT pin to the host controller to set the module into boot mode to
enable firmware updates via radio.
• Connect the MODE_1 pin to the host controller to switch between command and
peripheral only mode.
7. (Optional) Status indication
Connect the BUSY, LED_1 and LED_2 pins to the host controller to allow easy indication
of the status.
8. (Optional) Flash and debug interface
In case of custom firmware development, it is recommended to additionally have the pins
SWDIO and SWDCLK accessible in order to support a fail-safe update of firmware. A
standard socket on the customer's PCB for connecting a flash adapter can be useful for
debugging purposes (e.g. a JTAG 2*10 pin header with 2.54 mm pin-to-pin distance).
If the module has to be connected to a PC, a converter (TTL to RS-232 or TTL to USB) has to
be used. See chapter 3 for details on all pins. Please refer to the Proteus-III-EV schemes for a
reference design.
The logic level of the module is based on 3V. A 5V logic level must not be
connected directly to the module.
