Spresense + BP35A1 B-route communicator

Communicates with a low-voltage smart meter using B-route with BP35A1 (Wi-SUN module) and Spresense SDK (C/C++).

Notes

• Tested with Spresense SDK 2.4.0.
• Rename broute/broute_secrets.h.tpl to broute/broute_secrets.h and edit it. It contains B-route ID and password.
• To connect BP35A1 to Spresense, use TX/RX (D01/D02) pins. They are UART2 pins so it can be seen /dev/ttyS2 from Spresense.
• See SDK Setup Guide to add this app to build.
• This project uses VisualStudio Code + Spresense extension.
• See also my blog post (in Japanese).
