It gives you different options for PCBs. The one I have a Wemos Lolin D1 mini and I am trying to connect a D-Sun CC1101 via breadboard.
I followed the schematics from the github for the ESP8266 diagram and checked the SPI pinouts and all appears to be correct. In trying to troubleshoot, the github has a "Debug Service Tool" within the code. Within the serial monitor output I get a "Connection OK" in regards to the SPI, but a little garbage right before it, also the version and register values all show "FF"
Here's a screenshot of what I get and what it should look like:
I'm using the Arduino IDE, connecting the board through USB and selecting the appropriate COM port. When I select the serial monitor option to see output it was set to 9600 baudrate. I'm not sure what you mean by using another serial or softwareSerial? Do you mean a different IDE? different USB port?
I did try a different USB cable to rule out a cable issue, but got the same output. Thank you for your reply and suggestion.
Yes, that is the diagram/schematics I used to connect the PCB and the CC1101. I did as you suggested and connected the two without the breadboard and I am getting the same results. Any other suggestions?
