...and a little teaser: 2.4 will come with a set of new features some of you have been waiting for... stay tuned

Hi all,

I've been working on this project since some time, basically it's a GUI for controlling/updating/debugging a network of MySensors nodes. OTA functionality is supported via MYSBootloader - read posts for further instructions/troubleshooting or PM.

link updated: MYSController Version 1.0.0.3316 released

New features:

• support OTA FW update Sensebender board
• metric/imperial system I_CONFIG
• save nodes

Update via update button in MYSController or download here.

We are happy to announce the release of MySensors 2.1.0!

Major changes:

• Bug fixes and lots of improvements under the hood
• Added support for Raspberry Pi
• New transport layer: RFM95 (LoRa mode)
• Improved transport layer debug messages, see here.

For additional release notes, see here.
Documentation can be found here.

Happy New Year 2017! Have lots of fun and stay tuned for new features coming...

Sensbender, Janus, and HALO - they all support multiple RF modules, but the MySensors framework doesn't...until now

Example of a dualRF Sensebender serial gateway configuration - as simple as that:

#define MY_GATEWAY_SERIAL

#define MY_RADIO_RF24
#define MY_RADIO_RFM69
#define MY_RFM69_NEW_DRIVER // required for multitransport

// optional (but recommended)
#define MY_RF24_USE_INTERRUPTS

Some of the new features:

• multiple transports with RX queue
• GW does radio-specific routing, however, the network is still limited to 254 nodes
• RFM95 radio driver can run in RFM69 compatibility mode

This is still WIP (and will be for a while) but you can already get your hands dirty and test the PR.

Kudos to @scalz (Janus and HALO) and @tbowmo (Sensebender) for their cool boards!

Have fun!

1. Copy MYSBootloaderV13pre.hex (from MYSController/Bootloader folder) to the [Arduino IDE installation folder]/hardware/arduino/avr/bootloaders/MySensors/
2. Restart Arduino IDE, choose under Tools | Board | ATmega328 external 16Mhz with MYSBootloader or Tools | Board | ATmega328 internal 8Mhz with MYSBootloader depending on your HW settings
3. Connect USBasp to sensor node and select Tools | Programmer | USBasp and hit "Burn Bootloader"

Please use the AVR fuse calculator to retrieve the individual fuse settings. If you need to change frequency, BOD or other settings, change the fuse settings based on the fuse calculator.

OTA FW updates using MYSController:

1. Start MYSController, hit config and adjust settings (COM-Port & baud or IP address:port)
2. Hit connect: Connection to gateway should be established (gateway answers with gateway ready message), the node should appear and request an ID & FW.
3. Right-mouse click on that node, select assign FW, choose for example TimeReporter (demo firmware included in the MYSController/Firmware folder). Then click reboot and wait until FW is uploaded and node boots.
   TimeReporter firmware reports every few seconds some values such as time, millis, and voltage.

Custom firmware: compile your sketch and retrieve the generated .hex file (activate verbose mode in the Arduino IDE to get compiler messages and output path).

Copy .hex file to MYSController/Firmware folder and edit firmware_config.csv file according to the existing lines.

Hit "Refresh Repo" in MYSController and the newly copied firmware should appear in the Assign FW dropdown list, ready to be uploaded.

MySensors 2.0.0 will feature a refactored nRF24 driver having:

• reduced code size (-2kb)
• two-fold speed increase (processing)
• fewer register writing/polling
• fully defined init state
• SPI transactions

Please feel free to test MySensors 2.0.0-beta and provide feedback if you encounter any issues.

First impression of MySensors running on nRF24LE1. Reporting temperature / humidity from DHT22, VCC voltage and millis() timer.

This SoC has many interesting features (SPI, 2-Wire, Serial, GPIO, ADC, RNG, AES accelerator, etc. ) and sub uA sleeping modes - without the need to solder a RF module. However, flash size limited to 16kB - still more than enough for many (peripheral) sensors...

Readings in MYSController:

Compiling with SDCC and nRF24LE1 SDK.

Please read this excellent guide written by @scalz about MySensors OTA programming.

In brief:

Copy bootloader *.hex files (from Bootloader folder) to the [Arduino IDE installation folder]/hardware/arduino/avr/bootloaders/MYSBootloader/

Restart Arduino IDE, choose under Tools | Board | ATmega328 with MYSBootloader |, select correct board under Processor tab. Connect USBasp to sensor node and select Tools | Programmer | USBasp and hit "Burn Bootloader"
Please use the AVR fuse calculator to retrieve the individual fuse settings. If you need to change frequency, BOD or other settings, change the fuse settings based on the fuse calculator.

OTA FW updates using MYSController 3315 (included) (refer to @scalz's guide

Copy Arduino FW .hex file to MYSController/Firmware folder and edit firmware_config.csv file according to the existing lines.

Hit "Refresh Repo" in MYSController and the newly copied firmware should appear in the Assign FW dropdown list, ready to be uploaded.

Read this thread for discussions on MYSBootloader 1.3pre1

Have fun!

For completeness, here are the MYSBootloader instructions for OTA updates via MYSController:

1. Load gw sketch and connect arduino either via serial or ethernet port. No special bootloader needed for that part (i.e. standard optiboot bootloader will do the job).

2. Add these lines to the boards.txt file in your Arduino IDE installation folder (located somewhere like C:/Program Files/Arduino/hardware/arduino/avr)

5. Connect USBasp to sensor node and select Tools | Burn Bootloader

6. If everything worked well until here, you now have the MYSBootloader with the fuse settings from above burnt to your sensor node (16Mhz extXTAL or 8Mhz intRC, BOOTSZ 1024W, BOD 1V8).

7. Please use the AVR fuse calculator to retrieve the individual fuse settings. If you need to change frequency, BOD or other settings, change the fuse settings based on the fuse calculator.
   Important: The MYSBootloader.hex file was compiled for 16Mhz oscillators but it should also work at 8Mhz. If you intend to go below 8Mhz, I highly recommend to compile the bootloader with adjusted frequency settings.

8. Start MYSController, hit config and adjust settings (COM-Port & baud or IP address:port)

9. Hit connect: Connection to gateway should be established (gateway answers with gateway ready message), the node should appear and request an ID & FW.

10. Right-mouse click on that node, select assign FW, choose for example **TimeReporter ** (demo firmware included in the MYSController/Firmware folder). Then click reboot and wait until FW is uploaded and node boots.

@luizrrocha Can you post your sketch and (if available) debug log here?

@electrik Probably this is PubSubClient-related. Please provide additional infos:

• ESP board definitions version
• MySensors version
• GW sketch

@eiten A similar approach was used for a NRF5 +PA/LNA module: https://github.com/mysensors/MySensors/pull/1414/files#diff-7b958e4728831b83d2359a08827bcae1R64-R80

@eiten Would be helpful to see the debug logs (in rfm/sx verbose mode)

@eiten Yep, already saw this one. Based on the heltec implementation, the sx-registers are mapped to specific memory regions of the mcu. Would be interesting to have here a complete ASR-specific documentation...

@eiten Great job! Did you come across an "usable" ASR6501 datasheet - so far the information on this SoC is rather sparse?

@Avamander Can you upload both, the GW and node sketches from the working pair nanoGW/megaNode? Also, it would be helpful to see the full GW log from the non-working combination (nanoNode/megaGW) with MY_DEBUG_VERBOSE_RF24 enabled. If time allows, I'd like to reproduce and test your setup.

@FullMetal said in Node to Node Communication via Gatreway: Please upload the debug logs for further troubleshooting.

@Joerideman Glad to hear you finally got FOTA working - generally speaking, you can do both, serial FW uploads and FOTA, however, switching from FOTA to serial updates or vice-versa, you may want to clear the FW checksum stored in the EEPROM as instructed above. If your sketches are rather large or for prototyping/dev, I'd advise you to use the optiboot bootloader as the serial uploads are faster and the optiboot bootloaders uses less flash storage...

@Joerideman That looks already much better!

For the sake of completeness, here is the modified MYSBootloader source code.

Try clearing the EEPROM and then re-assign the FW
