Very first attempt to solder smd components on pcb with hot air soldering station. lots of mistakes but i m learning...

Hi Guys,

This is more of missing piece of puzzle, i have googled a lot to find some simple way to communicate with mysensors gateway but google this time failed me hence i decided to do this myself.

i have this script running over one year, yes i have made some improvements over the year and here is final version. its self explanatory, feel free to use it as you wish and modify and if you think some improvements can be made let me know my ears are all yours...

i have this raspberry pi base heating control that i built but i m not sure if i can share it here and what are the implications etc.... until then have fun and enjoy creating things (IOT)....

very first working Ethernet gateway

@avelo
thank you for suggestion, i have made prototype based on MIC5219-3.3
but sure TPS61291 / TPS61221 are good options. once i get pcb delivered i'll you know here.

10pcs/lot MIC5219-3.3BM5 SOT-23 MIC5219-3.3 3.3V MIC5219-3.3YM5 LG33 LDO Regulator

$0.72

i know this is old thread but here is what i have to deal with, truck load of different sd card ordered from amazon from different supplier, some full filled by amazon and some sold by amazon and all of them are fake and devil is in serial number so until you order more then one SD card you can never know if its real or fake.

working on GPIO MySensors Gateway

@thomasdr thank you for the info, and sorry for late reply, changing wait(500) to delay(500) worked.

Hi Guys,
i thought i better start new thread here instead hijacking someone's, i have uploaded all the code on http://www.pihome.eu i can answer any question you have here. its open source raspberry pi based smart heating control.

Thank you to all MySensorss Community other wise this project wasn't easy to make it wireless.
PiHome

First of all thanks to all who worked on this tutorial and bootloaders. i got fascinated about 8mhz and 1mhz with internal clock after reading this tutorial.

Some might say 1mhz 8 times slower then 8mhz hence need longer awake time to do perform task before it can go back to sleep and consumes more power but what i found: point is not it takes 8 times longer to perform task but it can run it on battery longer and on lower voltage when battery ist at its peak youth.

Anyway i wanted to share my experience and errors i had and the fix i found after googling around and spending hours trying to figure out what is going on.

if you follow instructions as it is then you will end up with second boards.txt file located at C:\Program Files (x86)\Arduino\hardware\breadboard\avr\boards.txt, this file contact info about ATmegaBOOT_168_atmega328_pro_8MHz.hex only. So far so good and it works but for some reason when i try to add 1mhz bootloader to C:\Program Files (x86)\Arduino\hardware\arduino\avr\boards.txt it just wouldn't work, the 1mhz bootloader wouldn't show in in board selection option but if i add info about 1mhz bootloader to "C:\Program Files (x86)\Arduino\hardware\breadboard\avr\boards.txt" then i could see option for "APM Optiboot internal 1MHz noBOD 9600baud" but when i try to burn this bootloader i get all sorts of error on burning bootloader, one of the error: Could not find tool avrdude (sorry didn't copy all error messages)

Then some forums suggest to start clean i.e uninstall Arduino ID and reinstall but simply uninstalling and reinstalling ID doesn't work you need to delete Arduino15 folder from following location(s) and reinstall Arduino ID:
C:\Users(username)\AppData\Local\Arduino15 or C:\Users<username>\AppData\Roaming\Arduino15 or C:\Users<username>\AppData\Local\Arduino15

What i think is best to keep your boards.txt file in one location and modify it and add bootloaders in it and this worked for me. Simply copy your bootloaders to C:\Program Files (x86)\Arduino\hardware\arduino\avr\bootloaders and modify C:\Program Files (x86)\Arduino\hardware\arduino\avr\boards.txt for additional bootloaders.
here is my boards.txt

i havent tested lora on serial gateway but i had issues using 3.3v arduino, for me fix was 5v arduino with logic converter.

very first working Ethernet gateway

Its not bug but a workaround just in case if any one is searching for solution. I was using WiFiManager with MySensors 2.3.1 for WiFi gateway and it was working fine and now i upgraded MySensors from 2.3.1 to 2.3.2 and my WiFi gateway sketch refuse to compile. for the time being workaround: You need to comment out two location in core/MyGatewayTransportEthernet.cpp
may be there is better way but this is quick fix.

Line 49 to 55

/*
#if defined(MY_GATEWAY_ESP8266) || defined(MY_GATEWAY_ESP32)
#if !defined(MY_WIFI_SSID)
#error ESP8266/ESP32 gateway: MY_WIFI_SSID not defined!
#endif
#endif
*/

Line 184 to 189

/*	(void)WiFi.begin(MY_WIFI_SSID, MY_WIFI_PASSWORD, 0, MY_WIFI_BSSID);
	while (WiFi.status() != WL_CONNECTED) {
		delay(1000);
		GATEWAY_DEBUG(PSTR("GWT:TIN:CONNECTING...\n"));
	}
	GATEWAY_DEBUG(PSTR("GWT:TIN:IP: %s\n"), WiFi.localIP().toString().c_str());*/

No, dimensions are different

just tired with different fuse settings bootloader.low_fuses=0xE2 but no success

Hi All,
i had some spare time and thought to play with OTA, i have burned bootloader with right channel and then upload blank sketch with, i have swapped the arduino just in case.

MySensors version 2.3.1
ESP8266 Gateway.
hex file size is 43KB
can any one see what i m doing wrong?

Blank sketch:

}

{

@zboblamont
i was expecting bit more range with 2dbi antenna, you are right i have to put better antenna gateway.
are you referring to
MY_RFM69_TX_POWER_DBM in sketch? on same note
what would be different between MY_RFM69_MAX_POWER_LEVEL_DBM and TX_POWER, i have tried MY_RFM69_MAX_POWER_LEVEL_DBM to 100u but made no difference in range.

@zboblamont, @mfalkvidd
Thank you both.

Relay Node:
Powered by 5v and using MIC5205-3.3v voltage regulator. 10uf & 100nf cap on radio
Arduino 8Mhz with RFM69CHW at 433Mhz

DS18B20 Sensors:
Powered by 3xAAA battery and using MIC5205-3.3v voltage regulator. 10uf & 100nf cap on radio
Arduino 8Mhz with RFM69HW at 433Mhz

Gateway:
Powered by 5v via micro USB to ESP.
ESP8266 with RFM69CHW at 433Mhz

First Test:
Gain:2dBi-3dBi
Wire diameter:0.6MM
Spring outer diameter:5MM
Total Length include soldering part: 34MM
Coil Turns: 28
Range around 20 to 30m while gateway was inside house.

Second Test
Gain:2dBi
Wire diameter:0.5MM
Spring outer diameter:5.5MM
Total Length include soldering part: unknown
Coil Turns: 17
Range around 20ish meter while gateway was inside house.

are there any customisations i can try in sketches to improve range? i.e max power level in sketch?

#define MY_RFM69_MAX_POWER_LEVEL_DBM 100u

adding following line to sketch fixed the reboot issues for me, but signal problem is still here

#define MY_RFM69_NEW_DRIVER```

@mfalkvidd thank you for quick reply. any chance of no signal after 20ish meeter (just outside the house) related to same issue?
