ESP-RFM69

Overview

RFM69 driver and web interface for the ESP8266. Note - this is fairly dated (old SDK), but should still work with 1.5.x.

Features:

• RFM69 driver for ESP8266
• NGINX-style HTTP server, serving files from SPIFFS
• RFM webapp for sending basic text, viewing received messages
• RFM69 OTA update utility, Moteino compatible
• SPIFFFS webapp:
  • Drag-and-drop file uploader based on websockets
  • Styled file viewer
  • Download files
  • Delete files
• SPIFFY-based ROM creator with gzip, html, css, js compression
• Web interface for WiFi
• Built with Espressif's NONOS SDK v1.5.2 and NONOS lwip 1.5.2 module

Bugs & Limitations:

• Have not tested anything other than 66-byte encrypted packet mode. YMMV
• File System uploader crashes on occasion. Probably not too difficult to fix but I haven't had time.
• Static Javascript is a bit messy and probably a bit buggy. Still getting the hang of web development.
• WiFi change and event monitor needs to be fixed or perhaps re-written
• This is not compatible with esp-arduino, but others have said that the RFM69 driver at lowpowerlab.com now works flawlessly.

Credits:

Any and all contributers to/authors of the various modules used in this project (see list below/LICENSE file). But particularly:

• Felix Rusu at LowPowerLab.com for creating the Moteino framework, RFM69 driver, and in particular all the work he has put in to Wireless Programming.
• Spritetm for his contribution of esp-httpd, and Israel Lot for his NGINX-flavor rework of esp-httpd.
• SPIFFS author pellepl for creating SPIFFS and making himself more than available for help and support.
• Espressif for the awesome, cheap chip and English documentation
• Max Filippov and Paul Sokolovsky (pfalcon) for open-sourcing this bad boy.

Installation

See Wiki.

Serial Monitor:

Default baud rate is 74880. After user_init is called, it goes to 115200. If platformIO is installed, serial monitor can be invoked as such (replace /dev/ftdi_esp with your com port):

platformio serialports monitor -b 115200 -p /dev/ftdi_esp

Moteino OTA:

See Moteino_OTA

MQTT

See MQTT. This is a very ugly, hard-coded implementation, sorry.

SPI Flash Info

The flash chips packaged with esp-xx modules can be of various sizes and come from various manufacturers. To get flash ID (as hex):

uint32 flash_id = spi_flash_get_id();
NODE_DBG("Flash_ID = %x", flash_id);

Layout:

• 0x000000 - 0x010000: 64KB - Bootloader, SDK
• 0x010000 - 0x080000: 448KB - Rom0
• 0x080000 - 0x090000: 64KB - Static FS (HTML, initial config)
• 0x090000 - 0x1DC000: 1328KB - Dynamic FS (All other files)
• 0x1FC000 - 0x200000: Unused (SDK config)

SPIFFS:

The address to flash SPIFFS must (I think) be on a proper multiple of the logical block size, and must not overlap with irom at all.
