@mfalkvidd
the psu provides 350 mA

[mfalkvidd]

ok. So from the log parser we see that the gateway sends a response to the id request, but the node keeps requesting a new id anyway.

Could you post the log from the node?

[mfalkvidd]

@swiss which capacitor(s) do you use? The nrf radio is extremely sensitive to power fluctuations.

at the moment i have no capacitors in place since i thought the communication was ok...

[mfalkvidd]

@swiss ok. No use to troubleshoot further without capacitors.

@mfalkvidd
ok sorry will ad them right now - sorry for using your time

thank you so much for kicking me into the right direction...

If understand it correct it got feedback from parent and is now requesting its id ? correct?
Is it correct that the ID should come from the Controller, in my case the Myscontroller ?
unfortunately i cant connect the controller to the Gateway, is there anything else i can check beside the IP and the port ?

thank you so much for your assistance would really love to make it happen...
matt

[mfalkvidd]

@swiss yes, that's correct.

What does the gateway log say when you connect the controller?

[swiss]

Here is the log of the gateway, it starts when i press "discover" on the software (after i connected)

but no node is found... and if i press discover again i got error 10054 in the software and the connection is terminated by the remote...

@swiss I would guess you are using Arduino AVR board version 1.6.19 (check in the board manager). If that is the case, the solution seems to be to downgrade. See https://forum.mysensors.org/post/72423

@swiss great! Thanks for reporting back.

How can I increase the number of blocks greater than 2048?

For STM32F407ZGT6, it may take up to 65k blocks. And in the controller, I understand it is a hard limit on 2048?

Is it OK?

No such warnings/detections for .282 version.

Hi all

I have an issue which I've documented in the Troubleshooting section. When I've searched for a resolution, this program has been mentioned. What I'm trying to do is get my controller to see the part of the gateway sketch that references a sensor that I added. Can this program help? What does this program actually do?

@Homer
Try it ;)
It's a handy controller software for debugging MySensors.

This is quite a nice piece of software! You have suggested you are going to release the sources at some point. Maybe that time is now? It would be great to see if it can be ported to Linux!

Bug in MYScontroller.
When I edit the file firmware_config.csv and set a version number with a decimal the output in the debug is wrong.
This is my file:

Type,Name,Version,File,Comments
10,Blink,1,Blink.ino.hex,blinking example
20,Tvattstugan-2,3,Tvattstugan-2.ino.hex,Testar Flash
30,Tvattstugan,2,Tvattstugan.ino.hex,Tvattstugan
40,Sovrummet,2.1,Sovrummet.ino.hex,Sovrummet

Note that I have 2.1 as the version in 40, Sovrummet.
But when I load the repo in MYSController v is 65535:

2021-02-13 17:06:37	REPO	FW "Blink" loaded. t=10, v=1, blocks=80, crc=0x46D4
2021-02-13 17:06:37	REPO	FW "Tvattstugan-2" loaded. t=20, v=3, blocks=1488, crc=0x6D13
2021-02-13 17:06:37	REPO	FW "Tvattstugan" loaded. t=30, v=2, blocks=960, crc=0xBB4F
2021-02-13 17:06:37	REPO	FW "Sovrummet" loaded. t=40, v=65535, blocks=936, crc=0x6AB3
2021-02-13 17:06:37	REPO	FW repository loaded. Items=4

And in the GUI the version is also 65535.

Actually there are two bugs.
If I add (sloppy I know) more empty lines at the end in the firmware_config.csv file I get this in the debug:

2021-02-13 17:13:35	REPO	FW "Blink" loaded. t=10, v=1, blocks=80, crc=0x46D4
2021-02-13 17:13:35	REPO	FW "Tvattstugan-2" loaded. t=20, v=3, blocks=1488, crc=0x6D13
2021-02-13 17:13:35	REPO	FW "Tvattstugan" loaded. t=30, v=2, blocks=960, crc=0xBB4F
2021-02-13 17:13:35	REPO	FW "Sovrummet" loaded. t=40, v=65535, blocks=936, crc=0x6AB3
2021-02-13 17:13:35	ERROR	2107-15-31 is not a valid date specification

Other than that, great piece of software. Thanks.
