9.3
Switching to HCI Firmware
New iWRAP firmware builds use a so called
unified firmware (
iWRAP firmware 2.1.0 and
newer
).
This means that the firmware contains all iWRAP firmware, RFCOMM and HCI
stacks. Selecting the active part is done by using PS keys and there is no need to reflash
the actual firmware as with older versions of iWRAP.
Switching can be done by using PSTool software.
1.
Connect the WTxx Bluetooth module as instructed in chapter 9.1.
2.
Change the following parameters to switch to HCI mode
a.
PSKEY_INITIAL_BOOTMODE
i.
0000 = iWRAP
ii.
0001 = HCI, BCSP, 115800,8n1
iii.
0003 = HCI, USB
iv.
0004
= HCI, H4, 115200,8n1
b.
PSKEY_UART_BAUDRATE
(Suitable value if H4 or BCSP used)
c.
PSKEY_UART_CONFIG_H4
PSKEY_UART_CONFIG_BCSP
(Suitable key/value)
d.
PSKEY_USB_XXXX
(If USB is used, configure the necessary
keys)
Note:
PSTool 1.21 or later is needed to change the parameters mentioned above.
