Beginner - what is wrong

xmonika

Thank you for the reply, I've connected it to the raspberry directly (pins 19-24) as described here https://www.mysensors.org/build/raspberry. I've been playing with adding a capacitor 47 uF to both node and raspberry with no efect. I don't have debug of the node, it is mysensebender micro - standalone.
One way could be to replace gateway direct connection or node with arduino and start tracking. At this moment I don't know if I shall focus my energy to track hardware or there is just some SW tweak/configuration I've missed.
What I know for sure - if I disconect battery (two AA) from the node and reconnect it again the gateway writes some READ,255-255-0 rows above - according to log parser indicating that the node is requesting for ID but the gateway doesn't respond (just my guess).

Could also be, if you post your code of the node we could take a look

xmonika

It is just new mysensebender micro out of the box, I suppose this code https://www.openhardware.io/view/1/Sensebender-Micro but I may be wrong. It has the same behavior - when GND and A0 connected during boot, the led blinks.

gohan

after #define MY_RADIO_NRF24 add
#define MY_NODE_ID 1

xmonika

Thank you for pointing my focus. I will try to experiment with that tonight.

Unfortunately I couldn't move futher because of not being able to upload sketch into the node. I've bought CP1202 USB-TTL/3V3 with DTR pin, downgraded Arduino IDE to 1.6.13, set up Mysensebender micro board, COM6, ATmega328 8 MHz and tried all the programmers available but everytime got

I've tried to switch Tx/Rx but not helped. I can track serial output, so there is some transfer

Any ideas how to setup IDE to push the code into node?

Hello, you should link TX of the adapter to RX on the board, and RX to TX.
Make sure DTR pin is corretly connected to DTR pin of the board and check all the wires you could have a defective one.
Selected programmer in Arduino should be AVR ISP mk2

gohan

If you have the red ftdi like in the picture, you can plug it straight in

xmonika

I have this one alt text .

The programmer I am using is called AVRISP.mkII, hope that is correct.

I have the RX-TX and TX-RX connected. I tried to switch them as well and suppose they are now correct because serial monitor works. DTR on the adapter is connected to the board. The board in self test mode works ok, so it is not damaged.

The output is the error as above. This is very frustrating I already have some experience with arduino but here after 20+ hours of experimenting I am not able to get out of point zero.

Anyway thank you for your patience and help.

@xmonika

The node requests an ID from the controller.. It is also shown in the MQTT on your raspberry pi, but the controller doesn't seem to reply to this ID request.

Have you configured OpenHAB to use MQTT for the mysensor gateway? Does the log in OpenHAB tell you anything?

Did you try to hardcode the node ID, as suggested by @gohan? If yes, could you post the node and gateway logs after this?

gohan

@tbowmo he tried to add the node id, but he is stuck with the uploading of the sketch :D

@xmonika then you start to see "uploading" in arduino IDE, try pressing the reset button on the arduino and see if it starts transferring the program.

xmonika

@gohan But I don't have arduino, I have direct connection between USB/TTL and sensebender micro like this (double checked)

CP1202 USB-TTL <-> MySensebender micro
GND <-> GND
3v3 <-> VCC (tried as well with AA battery without VCC connected)
RX <-> TX
TX <-> RX
DTR <-> DTR

Is there some way to manipulate reset directly on Sensebender micro? Like try to generate edge with the wire?

tbowmo

@xmonika

What target do you use in Arduino, when you're trying to program the sensebender micro?

xmonika

@tbowmo In IDE (Arduino: 1.6.13 - Windows 10), I have: "Sensebender Micro, Atmega328 8Mhz" (it is also shown in the code above) is that correct configuration?

tbowmo

@xmonika

And you can successfully see the debug log in your terminal program, from your sensebender micro?

xmonika

@tbowmo Yes, i.e. now I can see in the terminal all this:

Sensebender Micro FW 1.1req node id

tbowmo

@xmonika and still you can not upload a new sketch to this Pcb?

xmonika

@tbowmo Yes, exactly. By pressing Project Upload => not in sync and Upload error. By pressing Project Upload via programmer => just Upload error message. Here is my setup

tbowmo

I'm out of ideas right now.

Did you try a more recent version of the arduino ide?

xmonika

@tbowmo I will try to install all the drivers & IDE on diferent comp tomorrow. I already did the downgrade from 1.8 because of the note "Arduino IDE 1.5.x & 1.6.x compatible." in SB tech specs.
Anyway thanks for your help. I will have to invest more hours yet to reinvent the wheel but it is fine to have somebody to consult with.
