Use Berryboot AND fast USB drive to solve most of the problems related to corruption on SD card due power failures and number of write cycles. I have been using it for 2+ yrs now...

RE: MYSBootloader 1.3.0-beta.3
@tekka, Thanks for the link to the beta.4. bootloader. I have tried burning nodes using these and tested them by uploading the FW using MySController 1.0beta_b3316 (latest update meant for MySensors2.2.0) with SerialGatewaySketches using both MySensors2.2.0_rc1 and MySensrs2.2.0_pre1 libraries.
MysController doesn't seem to even recognize the Beta.4 bootloaded Nodes (Promini 5V16Mhz with default provided fuse settings from Makefile). The extra nRF chip wiring checks and precautions (0.01uF and 100uF Caps) have been taken. What might be the problem? How to debug when SerialMontitor cant be used? Any Network Sniffer link if that helps...
I guess the MySensors library version of the SerialGateway sketch may be posing a problem. Can you please help me with a link of the correct MySensors library version to use with beta.4 bootloaded nodes?
Any help will be appreciated...
RE: NodeManager: plugin for a rapid development of battery-powered sensors
When do you plan to release V1.7 ?
RE: 💬 FOTA (Wireless Programming)
@gohan Ook! Are you talking about installing MysController on Raspberrypi (I think not)? If you are going to run it on Windows and connect to Raspi Ethernet gateway remotely then using the the same option we can remotely connect to a serially connected gateway on Raspberrypi (using a USB port) from MysController running on Windows.
Are there steps somewhere to install MysController on Raspi [some Windows pre-installer running on Debian Linux]? I remember reading some Mysensors posts here a couple of years back(!!!), but cant seem to locate it now...
RE: 💬 NodeManager
@user2684, Sorry, couldn't revert to your query earlier as i was away building a small library.
Expanding onto my earlier post on the requested Power Management feature -
A simple switch will complete a circuit whenever its switched ON. This allows for placing the switch on the ground return wire too. So only a single GND-ON (Switched ON) will complete the circuit (without requiring an additional Vcc-ON switch).
Now, with a developer configured #DEFINE GND_ON_POWER =1 may be checked in NodeManager's PowerManagement functions to DigitalWrite(Digital_GND_ON_Pin, LOW)
for a switchON effect.
Additionally, To provide an extra current to a sensor (i.e. more than a ~10mA-20mA, a max safe current provided by an Arduino pin) an external power source (other than Arduino +5V0 OR +3V3) may be provided by that external power source (of course with with a common ground wire between Arduino and that powersource to complete the circuit.)
Also, with the current 2Wire PowerOn methodology, the VccPowerOn switch can provide only one positive voltage (that provided by Arduino Vcc, say +5V0) but not +3V3 (say) to the sensors. If some attached sensors require the other voltage (+3V3), then, this 2Wire PowerOn method will not help. Whereas, a single GND_On power methodology will still switch the circuit thus managing the Power to those sensors too.
[PS: Signal Voltage Levels will still need to be managed by the developer attaching those sensors to the node]
I think this simple feature will add on to the power of the PowerManagement functions.
Hope this clears some air ? Open to suggestions...
RE: Raspberry Pi SD Card wear out?
Try using Berryboot on SD card with a USB /pen drive. It will help in SD card wear out and power out cases. I am running multiple Raspis with multi boot option on Berryboot (added advantage ) for the last 2+years. Not much of a problem till date. Lots of power outages here... No UPS support!
