# When Bluetooth made connection, BT status LED will keep constant high, you can not write it low, notice. But you can read the BT status via this pin.<br />
<br />
== Serial Debuging ==<br />
* To receive MCU Debug Info, so USB-TTL <> MCU <br />
* Use USB-TTL Debug tool, for example PL2303 TX (Green Color), RX (White Color)<br />
* TX/G to right top pin, RX/W to right top second pin<br />
* To receive phone bluetooth end message, vice verse connection.<br />
=== Debug Note ===<br />
* Do not connect serial cable when send commands remote from phone, will block message.<br />
* Some module baudrate is 9600, 115200, 38400.<br />
<br />
* [[:Category:Bluetooth|Recommanded control phone APP see on this page.]]<br />
* [[:File:BLIO.zip|IAR for STM8 demo code available here.]]<br />
<br />
== Code Update ==<br />
<br />
* V1.12 get here [[File:BLKIOV1.1.hex.zip]]<br />
* V1.12 fixed button delay bug<br />
* V1.1 Custom Support PD2 PD4 as input, send message to bluetooth phone<br />
