Problems
|
||
|
|
--------
|
||
|
|
power consumption
|
||
|
|
no consumer page support(bug?)
|
||
|
|
no mouse wheel support
|
||
|
|
no paring management
|
||
|
|
no interactive auth method
|
||
|
|
|
||
|
|
|
||
|
|
UART hardware flow control
|
||
|
|
--------------------------
|
||
|
|
(iWRAP4 User Guide 9.5)
|
||
|
|
Hardware flow control is enabled by default and it should not be disabled unless mandatory, because without the hardware flow control the data transmission may not be reliable.
|
||
|
|
If the hardware flow control is enabled from PS-keys, but no flow control is used, the following steps should be implemented in the hardware design:
|
||
|
|
- CTS pin must be grounded
|
||
|
|
- RTS pin must be left floating
|
||
|
|
