Sensebender Micro
-
Well that didn't go well... assembling my first micro. Soldered on some pins for the FTDI connection, added power (2xAA holder), and soldered on the radio with cap. Then I put in batteries and brought up my domoticz page to see if it showed up. Started to smell something, looked down, and there's smoke coming from the battery holder. Grabbed the whole thing and yanked the wire free then dropped it in the sink. Not sure where I screwed up, but I sure shorted something!

Nope, didn't find the problem. Must be some solder that shorted the batteries out but I don't see it. Oh well... main problem is that was my only 2AA holder on hand, and it melted right through the end of it, so now I have to wait on more before I can try again. Bummer :)

You can feed it with just two wires connected to the USB FTDI TTL converter / programmer - have a look at this https://www.mysensors.org/hardware/micro
Available Pins - GND, GND, VCC (on the right) -
I am having an odd issue with one of my sensebender boards.
I have flashed 5 in a row, same sketch, same everything.
all look fine (and in english) in the serial monitor. but this one board displays different.
it does seem to work. but i can't figure out why it's showing up different in the monitor.
any ideas?Óåîóåâåîäåò Íéãòï Æ× 1.5óåîä: 2-2-0-0 ó=255,ã=0,ô=17,ðô=0,ì=3,óç=0,óô=ïë:1.5 óåîä: 2-2-0-0 ó=255,ã=3,ô=6,ðô=1,ì=1,óç=0,óô=ïë:0 óåîóïò óôáòôåä, éä=2, ðáòåîô=0, äéóôáîãå=1 - Ïîìéîå! óåîä: 2-2-0-0 ó=255,ã=3,ô=11,ðô=0,ì=17,óç=0,óô=ïë:Óåîóåâåîäåò Íéãòï óåîä: 2-2-0-0 ó=255,ã=3,ô=12,ðô=0,ì=3,óç=0,óô=ïë:1.5 óåîä: 2-2-0-0 ó=1,ã=0,ô=6,ðô=0,ì=0,óç=0,óô=ïë: óåîä: 2-2-0-0 ó=2,ã=0,ô=7,ðô=0,ì=0,óç=0,óô=ïë: óåîä: 2-2-0-0 ó=3,ã=0,ô=1,ðô=0,ì=0,óç=0,óô=ïë: óåîä: 2-2-0-0 ó=4,ã=0,ô=16,ðô=0,ì=0,óç=0,óô=ïë: éóÍåôòéã: 0 ÔåíðÄéææ :174.85 ÈõíÄéææ :154.00 Ô: 74.85 È: 54 óåîä: 2-2-0-0 ó=1,ã=1,ô=0,ðô=7,ì=5,óç=0,óô=ïë:74.8 óåîä: 2-2-0-0 ó=2,ã=1,ô=1,ðô=2,ì=2,óç=0,óô=ïë:54 óåîä: 2-2-0-0 ó=255,ã=3,ô=0,ðô=1,ì=1,óç=0,óô=ïë:97 ÏÔÁ Æ× õðäáôå åîáâìåä óåîä: 2-2-0-0 ó=4,ã=1,ô=23,ðô=2,ì=2,óç=0,óô=ïë:99 Ìéçèô: 99 ÔåíðÄéææ :0.01 ˆõíÄéææ :0.00 Ìéçèô: 99 -

What baudrate are you using? It seems like it's to much off, for the ftdi to decode it correctly. Have you tried to lower it to, let's say 9600 baud? And does it still do this?

Serial.begin(115200);
I have not tried 9600, but i've done 5 today all the same code.. no problems.
i have 4 others deployed from when i first bought these (when they came out) same code for them as well..
could be a bum board..idk. when i fired it up, i could see it in the controller software though. so it does seem to work. it just gives me that in the serial monitor.. strange for sure :) I'll let you know how 9600 works out. -

You don't use some exotic ascii encoding in your terminal? (not likely if you can switch to a different SenseBender and get sane output I suppose)
-
115200 is on the edge of what is possible with the 8Mhz that the sensebender is using. And it's a uncalibrated RC oscillator that's in use. So this one might be a bit off to the lower side (run 7.5Mhz for example) which could throw off your serial port a bit.
(But as @Anticimex mentions, it does look weird that the numbers are readable..)

@tbowmo @mvader it can still be a timing problem. Numbers in the ascii table have the most significant bits zero (they are in the range 0x3x and below) and since regular UART protocols transmit lsb first, the first bits may be within legal timing while the later bits are not, so the higher the ascii value, the higher the risk for corruption.

Playing with 2.0 I wanted to upgrade my sensebenders but I didn't find the sketch (neither in the main distribution nor in the examples folder).
Is there a version 2.0 compatible sketch?

@FotoFieber it is low located in the SenseBender repo in GitHub
Do you feel secure today? No? Start requiring some signatures and feel better tomorrow ;)

@Anticimex
Thx. This is an old version. I found a newer on my hard drive (old development branch). As I do only need temp/hum, I reduced the sketch and it is working fine. -

Yup, it was moved over from development branch on the release night. So should be the latest and greatest

Hi!
I am in process of upgrading my Sensebenders to V2.0 and like to enable the OTA function.Who can give me some pointers on the capabilities of OTA for this Sensebender Micro board?
I know that has external flash for this purpose, but i am stuggling a bit finding how to use it.
So I am keen to read information on dependencies of the Sensebender sketch as well as the controller options.
My environment:
6x Sensebender
Wifi based Gateway
Domoticz as controllerThings I like to know:
- Is my sensebender shipped with optiboot bootloader? (have them about 1 year now)?
- do i require special Gateway software? (i noticed a sketch called something like GatewayESP8266OTA)
- what can i expect from Domoticz? probably not much, so do i need to connect to another controller (e.g. MYSController) to perform an update?
- What controller is advised for the standard bootloader (optiboot bootloader)?
I am sure those things are discussed in the past, but I was unable to find it.
Would be great if somebody can share a howto or wiki on this topic.thanks in advance

Sensebender is delivered with "DualOptiboot" which uses the external flash.
To enable OTA with 2.0.0, you have to compile your sketches with
#define MY_OTA_FIRMWARE_FEATUREenabled. For controller / Gateway, you need something else than domoticz. I haven't tried OTA firmware upgrades myself yet, so I do not have any experience with what works, and what doesn't work, other than the fact that domoticz doesn't support OTA..

Today I soldered the headers to a new sensebender and try to start it. I've uploaded the 2.0 example but it can't find the gateway:

But this one can't communicate. Does anyone have any idea, what might be wrong?
