GENERAL INFORMATION
This chapter contains a lot of useful information about iWRAP and its usage.
9.1
Changing Parameters over RS232 with PSTool
PSTool software allows the user to change the internal parameters (PS keys) of the
module. Most of the parameters should not be touched, since they can affect the
performance of the module. On the other hand, there are some useful parameters, which
can not be accessed from iWRAP, such as hardware flow control, host interface parameters
and so on.
Notice that although the parameters can be easily changed over the UART interface,
incorrect configuration may prevent iWRAP from working and block any other than SPI
communications with the module.
iWRAP has a useful feature called AutoBCSP. With AutoBCSP, iWRAP can automatically
recognize BCSP (BlueCore Serial Protocol) traffic and is able to interpret it. BCSP can be
used to change the internal parameters and is also supported by the PSTool software.
To change the internal parameters, proceed as follows:
1.
Connect an RS2323 cable between your WTxx Bluetooth module and your PC
2.
Power up the Bluetooth module
3.
Open PSTool application
4.
Use the default connection settings:
BCSP
,
COMn
and
115200
5.
Change the needed parameters (remember to press ‘SET’ after changing the
parameter value)
6.
Close PSTool and reset WRAP THOR
iWRAP is automatically activated after a reset, unless parameters affecting iWRAP
operation are changed.
NOTE:
When using BCSP, the UART baud rate does NOT depend on the configuration
set
with “
SET CONTROL BAUD
” command, but is defined by using PS key
“PSKEY_UART_BAUD RATE”. By default, the parameter value is 115200 bps.
The AutoBCSP feature only works if PSKEY_UART_BAUD_RATE and “SET CONTROL
BAUD” have same UART baud rate values values.
PSTool can be also used through the SPI interface. A cable called
Onboard
Installation Kit
is needed.
