Hello ST Team,
We are using the STEVAL-MKI109V3 as the motherboard and STEVAL-MKI208V1K (IIS3DWB vibration sensor) as the daughter board.
We currently communicate using the USB virtual COM port at 115200 baud and send ASCII commands such as:
*SETDB208V1
*ZOFF
*W10A2
*DEBUG
*STOP
These commands work correctly over USB.
Objective:
We would like to print the data serially using the same commands, but over Bluetooth, not USB.
The accessory board STEVAL-MKI115V1 is no longer available in the market.
We tried using an HC-05 Bluetooth UART module, connecting it to BT_TX and BT_RX (J9 connector), but it did not work, so the default MKI109V3 firmware support UART input/output on the BT_TX / BT_RX pins ?
- Can we connect a standard Bluetooth SPP module (HC-05 or similar) to BT_TX / BT_RX and send the same ASCII commands (*SETDB208V1, etc.) wirelessly?
- Or is USB the only supported communication interface in the default firmware for command parsing and data streaming?
Any guidance or documentation regarding UART usage or supported alternative Bluetooth modules would be greatly appreciated.
Thank you.
Raj
