Mongoose OS 2.13.0

New Features

Focus of this release is initial support for Redpine Signals RS14100.

It's a very versatile chip with a lot functionality. For now we have the following:

• UART
• GPIO input/output (no interrupts)
• Filesystem
• OTA
• I2C (bitbang)
• WiFi station

WiFi AP, BT, Zigbee are TODO. As always, users can utilize SDK for missing bits of functionality.

NB: Currently Docker image is private due to SDK being available under NDA.

• mos: Add atca-gen-cert - command to generate ATCA key and cert in one go ([cesanta/mos-tool@d896418]
  (cesanta/mos-tool@d896418))
• mos: Add --cdef VAR=value (cesanta/mos-tool@ea01910)
