Hi, I just got my feet wet by building a Solo device using Bluetooth. I could set the baud rate on the module, and the Android app connects successfully, but there seems to be an issue with the RX5808 module.
The RSSI value reported by the app seems to move up slowly as the radio module heats up (value moves within the 80 - 90 range). When I manually disconnect the RSSI pin (A3 on the Arduino) I see that value changing, so I am assuming everything works correctly on the Arduino side.
The module I got it this one. It looks like it is already working in SPI mode, but just to be sure I opened the lid and checked, the SPI_SE pin on the MCU is missing an SMD resistor. So it seems that it indeed is SPI ready.
Now, when I probe the SPI_CLK pin (CH3 on the PCB) I don't see a clock signal. Is it because the clock signal is only there when the board tries to communicate with the radio module? More generally, how would you go about debugging this?
