💬 Sensebender Micro

Just leave it on..

NailMan

Hello!

Help me understand why the sketches are not loaded in Sensebender Micro - there is a synchronization error:
avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x82
....
avrdude: stk500_getsync() attempt 9 of 10: not in sync: resp=0x82
avrdude: stk500_recv(): programmer is not responding

FTDI connected via 3.3V jumper
Another device built on the SB Micro with SB bootloader is also not flashed with the same error, but on the PC of my friend, sketches successfully loaded into the device and on my PC are given the correct data when working sketch
device and serial port are selected correctly
mySensors Lib and device packs(AVR, SAMD) installed with standard lib and device managers(and also added path https://raw.githubusercontent.com/mysensors/ArduinoBoards/master/package_mysensors.org_index.json in the settings menu)
at the same time if I take a pure Pro Mini and load into it any sample sketch of mySensors package - it will successfully do it and will work.

What am I doing wrong and how do I get the Sensebender Micro to take sketches?

tbowmo

@nailman

Did you select the sensebender micro as target in Arduino? Is it the same FTDI device that is used on both computers?

NailMan

@tbowmo
Yes, of course, I chose the target device "Sensebender Micro -> "Atmega328p, 1mhz" and "Atmega328p, 8mhz"(for device (RGBW controller) based on SB Micro with 8Mhz quartz resonator).

I tried three different FTDIs.

With any other Arduino (with native loaders) there are no problems with these FTDI adapters.

alexsh1

@nailman At what Mhz does your RGBW Controller is running now?
It seems to be the problem is in identifying the correct board.

If I have a board running at 1Mhz and try to program it at 8Mhz, similar to your error would come up, i.e. not in sync

tbowmo

Unless the bootloader is reprogrammed, then it defaults to 8mhz, and you have to actively set registers to run at 1mhz in your sketch.

Do you have a ISP programmer? If yes, could you make a memory dump, and send it to me?

Hello,
Coming back to the battery powering topic: I was checking some SlimNode code and it uses #include <Vcc.h> library to report battery level. I can see in that the example code above doesn't use it. Does anyone know what is the difference? Which is better?
Thanks,

tbowmo

@joaoabs

Could you post a link to the code from slimnode?

joaoabs

Hi,

The slimnode original thread has a few (not sure anymore which example I'm using now because the thread is huge and I've lost track of it)
Here is one example:
https://forum.mysensors.org/topic/2067/my-slim-2aa-battery-node/306

and other:

@joaoabs

The library use the exact same method to read VCC, as the Sensebender Micro example. It's just the functions that is extracted into a library (which I think have been done by @Yveaux )

NailMan

@tbowmo
I apologize for the delay in replying, I was very busy with work.

It turned out to be some mystical incompatibility of the FTDI and Sensbender Micro or a device based on its loader. Three versions of my FTDI refused to work with Sensbender Micro, but they worked with regular Arduino, and the fourth one, bought on AliExpress, works perfectly normal. Externally, all the same, only those that do not work with Sensbender Micro, the labeling of the chip differs slightly in the quality of engraving on the plastic.

Maybe it's fake or some kind of non-standard chips.

alexsh1

@nailman There are a lot of fake FTDI modules. Some are labelled FTDI other claim to be FTDI but are CH340. Some have DTR others RST and good ones like Adafruit Friend it is selectable.

My recommendation is do not try to save a few bucks here. Spend money on a good quality FTDI adapter like Adafruit Friend.

Hi,
I'm using the mysensor lib for a while but I recently run into problems. I've some arduino pro minis running with dht22 sensors which send their data over nrf24 to an mqtt ethernet gateway.
But maybe someone can help me with this one: I have build my own sensebender-micro modules. First of all I programmed the fuses of the mega328p as follows: lfuse: 0xE2, hfuse: 0xD2, efuse: 0xFE. Then I've programmed the DualOptiBoot Bootloader to them, everything worked fine so far, I can upoload sketches from the Arduino IDE via FTDI Programmer. The Problem: When I upload the official example sketch and watch the serial monitor I just see the MySensors splash screen. It seems, that the sketch does not even run into the setup routine. This starts to make me crazy, since I do not even know where to search. If I upload other sketches (basic blinking led, serial port examples or the passive node example from mysensors) it shows that my hardware in general seems to work. When I enable debug this is the output:

Even the NRF24 connection seems to work. This is the output of my mosquitto broker when running the passive node example:

Hi @flybysun, welcome to the forum!

!TSM:FPAR:NO REPLY

means that the sensor node does not get a response from the gateway. What type of gateway are you using? Could you post the debug log from it?

If you haven't already, check https://forum.mysensors.org/topic/666/debug-faq-and-how-ask-for-help/ for the most common problems and how to troubleshoot them. (Hint: Power supply is the most common problem, the nrf24 is extremely picky)

flybysun

Hi @mfalkvidd, thanks for the warm welcome!
So, tonight I'll give it another try. I soldered 1000uF above VCC and GND on both the sender and the gateway RF Links (that's all I could find here for now). Still got issues. Here are the logs from my gateway, when it starts up and receives values from my working sensor I had before:

This looks okay I guess, now this happens when I activate my SenseBender Micro:

I filled this logs into the Log Parser and found out that the Gateway receives informations on the sensor node, but when it responses it does not get the ACK from the sensor node.

May I have a faulty NRF24? I just received a new batch from AliExpress and this my first try with them.

My gateway is an Arduino Uno Board with the Arduino Ethernet shield and on top of that equipped with the long range version of the NRF24 Board (the one with the antenna).
The SenseBender is equipped with the "normal" smt version as suggested. The sensor nodes which are working right now were equipped with the smd version of the nrf-board.

I also found out that the initialization of the sensor and the gateway has a different Core initialization, different capabilities (CP). I looked through the API, but didn't find what CP=RNNGA or CP=RNONA stands for.

Any suggestions or ideas?

@flybysun information on capabilites is available at https://forum.mysensors.org/topic/7718/mysensors-capabilities-deciphering and https://www.mysensors.org/apidocs/group__MyCapabilities.html

tbowmo

@flybysun

what is the "official" firmware that you upload to the atmega? If it's the sensebender micro fw, then please observe that this is meant to run with a Si7021 sensor, and not DHT22, so unless you modify things, it won't run without that sensor onboard..

flybysun

@tbowmo
I have a 1:1 build of the sensebender micro, including the Si7021. Something I definetly will try tonight is to change the the radio modules with one of these I had before (and are working). I've just discovered this here:
https://forum.mysensors.org/topic/1153/we-are-mostly-using-fake-nrf24l01-s-but-worse-fakes-are-emerging

With "official" firmware I mean the Arduino Sketch which is included on the hardware webpage:
https://www.mysensors.org/hardware/micro

flybysun

@mfalkvidd @tbowmo
So folks, I finally got it to work. It really seems to be a problem with my radio modules. When I change my PA module on the gateway against one of these I ordered for the SenseBender Micro, everything works fine. But I still don't understand why my pro mini with the smd radio was able to send the data to the pa module, while the sensebender connected to a smd version still didn't work.
Is there anything special on the PA Version, that I've missed? I wonder if I can live with that now, I thought the PA Version has a bit more sensitivity and gain and would be better as the central gateway unit.

mfalkvidd

@flybysun the PA version draws much more power than the non-PA version (5x more if I remember correctly). If the power supply can't deliver clean power (without ripples or sudden dips), the radio will malfunction.
