My Sensor node "motherboard" (MySensorsNode)
-
I've got it working BUT I've very strange "solution". I'll write it down maybe someone be able to explain me what's going on:
I've 3 versions of "test program" 1.0, 1.1, 1.2 (actually the only difference is sketch number).
- I'm uploading manually with avrdude DualOptiboot from "Mysensors board package" (uploading using gui not working - gives strange error about fuses).
- I'm uploading (using USBasp and Arduino GUI) program version 1.0: program is working but "Reboot" command send from MYSController gets arduin into endless loop during "boot"

- One again I program bootloader using command:
avrdude -c usbasp -p m328p -u -U flash:w:optiboot_atmega328_pro_8MHz.hex
- Surprise, surprise: version 1.1 present and running, reboot command WORKING!
- After these I can program freely (using OTA) other versions of program (e.x. 1.2 or even "start version" 1.0)
I'm making some STUPID mistake but I can't find it......
@bilbolodz hm, sorry. Can't really help there. The board should be SenseBender compatible so what ever flow is described for that board (and bootloader designed for that board) should work on this. But perhaps the fact that this one has a pro mini and not just a vanilla atmega cause it to behave differently in some way.

@bilbolodz I had also problems with DualOptiboot and OTA. It is very poorly documented. As I understand how it works, If you burn the bootloader first and then the program You actually erasing the bootloader that you burned before (thats why it is in "endless loop"). The bootloader must be burned after the program is already on the external flash, so it can load that program into the internal memory. To do that:
- upload the program to the board
- fire the ota update to write the same program to the external flash
- program the bootloader
after that you will have the bootloader and OTA working.

I've made some test. It looks that bootloader is "damaged" ONLY if sketch is loaded using programmer (USBASP in my case). If sketch is loaded via serial and bootloader all is fine. So correct usage should be:- Program DualOptiboot bootloader using programmer
- Upload sketch using serial port and DualOptiboot bootloader

@bilbolodz LOL, You are absolutely right :D thats why it is called "Dual" :P because it can also boot from the serial port ... thanks !!

EDIT: BOMs are now uploaded as well. I have to inspect the gerbers one more time but it is close to manufacture now :)
@Anticimex
Could you please:- Point me to drop in replacement for DMP3056L-7? It's hard to get in my area...
- Tell where can I buy SI7021 chip?

@bilbolodz said in My Sensor node "motherboard" (MySensorsNode):
SI7021
fo the transistor search for P-CHANNEL MOSFET with Low On-Resistance (the lower the better, the DMP3056L has 500mOhms) and the transistor must be rated for voltage grater than your power supply (Drain-Source Voltage parameter in datasheet, which is negative value but think of it as it would be positive)
-
@bilbolodz you find all sourcing information I have on github
@Anticimex I've checked it but in most cases all sources you've mentioned have very expensive shipment to Poland.
How about DMP3056L-7 replacement? I've found it on aliexpres but shipment are twice such expensive as 35 pieces of transistor. -

I cannot help on country specific sourcing alternatives. It would be impossible for me to create a list for the cheapest sourcing alternatives for every country. You have all part information in the BOM. So it should be relatively easy for you to search the parts. And if you want alternatives, do a parametric search at your preferred suppliers.

Do you have suggestion how to mount RFM69 radio module? "Standard" 2.54 gold pin won't fit....
@bilbolodz well, no it is 2mm pitch.
