Use of the Data Rate Jumper
The purpose of this jumper is to access the A^RF32 module by forcing the UART
data rate in case of unknown UART parameters.
Data Rate Jumper
(red link)
In case of setup error while evaluating,
communication with ARF32 module can be lost
(bad UART parameters setup).
By connecting the “Data Rate Jumper”, UART
settings are forced to :
• Data rate = 9600 bps
NB : other settings (Parity, Stop bit & Flow
control…) remain the same and have to be
check for recovery values..
It becomes possible to re-program the “Non volatile Settings” to access again
the ARF32 Module. When done, jumper can be removed.
