11. Remote GPIO control
The Proteus-III allows to control free GPIOs via remote access. Chapter
7.7
contains the
description of the necessary commands.
To use the remote GPIO control feature of the Proteus-III, the GPIOs of interest must be
configured first. This can be done in two ways. Either by the local host (see figure
12
), when
the radio module is in idle mode (not connected via Bluetooth
®
LE), or via the connected
remote device (see figure
13
).
In case of the local host, it must send a
CMD_GPIO_LOCAL_WRITECONFIG_REQ
command to the
radio module via UART . In case of the remote device, it must setup a Bluetooth
®
LE con-
nection to the remote device first and send a
CMD_GPIO_REMOTE_WRITECONFIG_REQ
command
to the radio module via Bluetooth
®
LE afterwards.
The configuration is stored in flash memory, such that it is retained also after a device restart.
It can be reset to default by using the
CMD_FACTORYRESET_REQ
command.
The configuration can be also read out using the respective commands,
CMD_GPIO_LOCAL_
READCONFIG_REQ
via local host or
CMD_GPIO_REMOTE_READCONFIG_REQ
via remote device.
If the configuration has been done, the configured GPIOs can be controlled by the local
host controller or by any remote device.
To control a GPIO via local host controller just send the respective commands,
CMD_GPIO_
LOCAL_WRITE_REQ
for setting GPIO output values (see figure
16
), or
CMD_GPIO_LOCAL_READ_
REQ
for reading GPIO values (see figure
17
). Each time the GPIOs are written via local host,
the connected remote device is informed using a
CMD_GPIO_LOCAL_WRITE_IND
message.
To control a GPIO via remote device, first setup a Bluetooth
®
LE connection to the radio
module and send the respective commands,
CMD_GPIO_REMOTE_WRITE_REQ
for setting GPIO
output values (see figure
18
), or
CMD_GPIO_REMOTE_READ_REQ
for reading GPIO values (see
figure
19
).
Each time the GPIOs are written via remote connection, the local host is informed using a
CMD_GPIO_REMOTE_WRITE_IND
message.
