If you want to use your own macro, make the following statement first in the macro, if necessary:
Tera Term Macro command
Contents
Set echo 1
Enable local echo.
Set debug 2
Displays the display mode in hexadecimal.
When the hexadecimal display is displayed, it is possible to wait for
the hexadecimal character by the wait command etc.
When sending binary data with the Send command or similar, append $ to hex.
Example: Sending "ABC": “send $41 $42 $43”
For more information, refer to the "TTL Command Reference" in the help of Tera Term.
It is also possible to create binary data and send data from "file" to "file".
If you do not use Tera Term and want to communicate directly with the MCU etc6.2., refer to Appendix 6.2.

6.2. Connect UART directly from through Hole
BP359C has a through-hole as follows.
The terminals (TXD, RXD, etc.) required for BP35C0-J11 UART can be extracted from the through-hole group 1 and through-hole
group 2 as described in on the BP359C board.
Please note that when using the UART terminal of through-hole group1, it is necessary to connect the JP1 and enable the terminal.
Through-hole 2, it is possible to take out the UART terminal from BP35C0-J11 without switching the JP1.
It is also possible to connect the BP35C0-J11 to the host MCU and the through-hole by the wiring as follows. Please try to evaluate
using the MCU without using Tera Term etc.,
* In the figure, BP35C0-J11-T01 is used, but the process is the same when using BP35C1-J11-T01.
