11. TROUBLESHOOTING
Q: I get no response from iWRAP?
Make sure your terminal settings are correct. Use PSTool to check the UART settings from
the WRAP THOR Bluetooth module and make similar settings to your terminal software.
Check also your ECHO MODE settings. If you have set ECHO MODE to 0, you should not be
able to see any responses.
You can also use iWRAP update to restore the firmware and default settings.
Q: I changed ‘UART Baud rate’ key, but it didn’t seem to work?
UART baud rate is stored now into user keys instead of ‘ UART baud rate’ key. Delete
‘ User configuration data 26 ’ in order to return back to default settings 115200,8n1 .
Notice also that if you change the baud rate with “SET CONTROL BAUD”, it does not affect
the baud rate you need to use with PSTool, if you want to access parameters. This baud
rate is defined by the
‘UART baud rate’ key.
AutoBCSP requires that iWRAP baud rate is same as ‘ UART baud rate ’ key.
Q: Data coming from the UART is corrupted
If you are using ‘Deep sleep’ the minimum baud rate that can be used is 19200. Lower
baud rates will corrupt the data.
Q: I’m missing characters when I type ASCII commands.
If deep sleep is used, the first character written to UART wakes the module from the ‘Deep
sleep’ and that’s why the character is lost. There are two ways to overcome this problem:
1. If you command iWRAP with a micro controller or processor, add ‘space’ or ‘line
break’ characters in front of every command.
2. In PSTool, set parameter ‘EXIT deep sleep on CTS line activity’ to TRUE. Now ‘Deep
sleep’ does not lose characters any more, but current consumption will increase.
