I have a HM-10 BLE connected to my arduino over UART.
HM-10 TX - Arduino Pin 10 softRX HM-10 RX - Arduino Pin 11 softTX HM-10 GND - Arduino GND HM-10 VCC - Arduino 3.3V HM-10 STATE - Not connected. HM-10 BRK - Not connected.
My rookie assumption of a spi device was that I should be able to connect to it. And then set a pin high/low when I want to talk to it - i.e. chip select (CS)?
Clearly HM-10 BRK is used to signal a break in communication. However I though that HM-10 STATE might be CS, but the HM-10 responds regardless of weather STATE is high or low. Any idea's as I want to connect more than one SPI device to my arduino ....
