Customer:
I’m trying to use Inkplate 5 in peripheral mode. I tested it with the Weather station example and it worked correctly. I downloaded Inkplate5V2_peripheral_mode with all attached libraries.
I soldered GND/RX/TX with wires and connected GND to GND, RX to TX, and TX to RX of the Arduino Nano ESP32 BLE.
When I connect Inkplate with my computer, Serial monitor shows output. I downloaded a simple code on my Arduino and it also shows serial output, but the Inkplate doesn’t display anything.
I tried to send commands directly to Inkplate via my computer’s Serial Monitor:
CLS
TXT 40 40 Bonjour
SHOW
Nothing happens. What am I doing wrong?
