0.4.2 Release for Photon

This release contains a fix for device configuration becoming unwritable, causing new Wi-FI settings to not be remembered.

Steps to Apply this release

• download system-part1-0.4.2-photon.bin and system-part2-0.4.2-photon.bin
• First put the device in DFU mode
• open a terminal window, change to the directory where you downloaded the files above, and run these commands:

dfu-util -d 2b04:d006 -a 0 -s 0x8020000 -D system-part1-0.4.2-photon.bin
dfu-util -d 2b04:d006 -a 0 -s 0x8060000:leave -D system-part2-0.4.2-photon.bin

Changes

FEATURES

• EEPROM storage of custom data types via EEPROM.put() and `EEPROM.get()'
• When the device is in safe mode, the LED breathes magenta
• attachSystemInterrupt() allows hooking key system interrupts in user code.
• DMA-driven SPI master
• UDP.sendPacket() method avoids buffering data when the user can supply the entire buffer at once.
• [Photon] SoftAP setup can be done over HTTP
• platform-neutral fast pin access 449
• [P1] Serial2 support

ENHANCEMENTS

• [Photon] The system firmware updates the bootloader to latest version
• [Photon] The system write protects the bootloader region.
• UDP uses dynamically allocated buffers
• PRODUCT_ID and PRODUCT_VERSION place these details at a known place in the firmware image
• DFU mode and serial firmware update can be triggered by setting the line rate.

BUGFIXES

• Serial1.end() hangs the system
• Malformed CoAP acknowledgement message in cloud protocol.
• SPARK_WLAN_Loop() was not linked. (Workaround was to use Spark.process())
• UDP doesn't send anything to the device until UDP.write() #407
• Divide by zero now caught and causes a SOS.
• Floating-point support for sprintf() reinstated
• Fixed WICED DCT becoming unmodifiable
• Fix UDP.parsePacket() not receiving any data on the Photon #468
