Blueprints will help bridge the communication between the embedded team and the Cloud team. Like real blueprints, Golioth Blueprints help to map out how things should be built.
Sometimes you don't have extra pins for TX/RX, the UART is already in use, or you don't want to upset critical timing by printing out messages. Real Time Transfer (RTT) is perfect in these situations. It uses the J-Link programmer to transfer console debugging output, without getting a UART involved at all. Good news, it's easy to use with Zephyr!
