hi, yes it was very simple :-D the gateway has worked fine in this time, i thought that when nothing shown in serial monitor that the gateway dont work, but it did it, after i connected the gateway to FHEM (my controller) i saw that FHEM connects t mys Gateway.
So it worked all the time

Hello together,
i have bought a sensebender micro to test as temp and humidity sensor. I use the example sketch from sensebender, and for test i used a cd2032 battery but the battery is after 14 days empty.
So i have to optimize my code and would like to ask you which settings are you using for battery nodes.
How often do you transmit the temp / humidity?
Which threshold for changing the temp / humidity?
Thanks a lot
Greets Eddie
@Michiel-van-der-Wulp
thank you i will test it the next few days
@Michiel-van-der-Wulp
Can you tell me where in the code is the switch to 1 MHz? I still have the problems that my node dosnt send anymore. It works for several hours but after then it dont send anything.
In programming i am not good, and so i cant find the switch.
Thank you very much.
Greets Eddie
@qqlapraline
oh yes it does! It explains why i get the € signs in the serial monitor. But why does the node not send to my FHEM Controller? Depends it also on it, that the node switch to 1 Mhz and cant send anymore?
Thank you very much for your answer, its very helpfull.

i have just tried it again, it worked for 20 minutes. After them i get this output:

ok one more thing i found, when i close the serial monitor and start it again, i get the correctly output again, and i see in fhem the new readings.
but i cant understand what happens why stop the node to transmit the correct readings
Hey together,
i have an problem, i had some troubles with the space on the sb micro, i have removed the #define my_debug that solved my space problem, but now i have observed that the node is starting and sends few times the temp and humidity but after the few times nothing happens anymore.
i observed, when i hold the sensor in the fingers so that it will be worm, and start the node then it sends all minute the temp, but when the temp goes down to the room temperature then the node should send only when the humidity or temp changes over the threshhold, so in the room i dont have much changes and i think that when the node does not send about a longer time, that the the problem comes up.
I tested it in some different distances, on another floor but in very short distance too. I dont think that is a radio problem.
What do you think about?
The Problem is, that i cant debug the node because i disabled it because of space problems.
Thank you

@Anticimex
sorry i didnt let hear anything from me for the last few days.
i had the same problems with compiling the sketch. It depends on the signing. When you remove the #define MY_SIGNING_ATSHA204 the you can compile but when the singning is defined you get an error until you remove this line:
#include <drivers/ATSHA204/ATSHA204.cpp>
i have removed the line and defined the signing and for me works the singing and encryption.
but i have an another problem, i dont know if i am right here or i better have to post in the sensebender micro forum, i posted that i had some troubles with the space on the sb micro, i have removed the #define my_debug that solved my space problem, but now i have observed that the node is starting and sends few times the temp and humidity but after the few times nothing happens anymore.
i used the stable lib and comiled the sketch both features are now working encryption and signing! Thank you very much!!!!! I will try to update the example lib and try again.
I got just the next problem the space from sensebender micro is not enought to use all three features signing, encryption and ota. When i use AES and Signing i get over 109%, when i use the example sketch temp and humidty meassure.
Greets Eddie
Hey together,
i have a question, because i have some capacity troubles. I used the example sketch from sensebender micro that meassures the temperature and humidity but i have additional activated the signing and encryption and now i got over the availible space 109%.
use anybody from you all the features? what i have to do?
thank you
@Anticimex
its combined from two example sketches sensebendergateway and gatewayw5100 example sketch
@Anticimex
Hi, i just tried it out and now it and it has worked! The Aes key is stored correctly! BUT i get now an error on compile the gateway sketch
C:\Users\meddie\Documents\Arduino\SenseebnderGW_LAN_NRF24\SenseebnderGW_LAN_NRF24.ino\SenseebnderGW_LAN_NRF24.ino.ino: In function 'bool testEEProm()':

i could use the stable lib again then it should compile, but i think you would like to know that an error occours.
Greets Eddie
@Anticimex
thank you very much for your support and for your patience with me!!!!
i just tried and the signing is working fine!!!!
i look forward to try the encryption! i
@Anticimex
and this is the serial output:
This key will be stored in EEPROM as AES key:

@tbowmo
sorry can you say me please what i have to add to the sketch that will store my aes key on the sensebender gateway?
I am a very very noob
thanks
@Anticimex
the troubles i have on sensebender gateway its a samd. On the micro (avr based) works fine.
On the gateway i didnt upload a sketch between. I have uploaded the personalizer sketch and after them i tried the unmoded personalizer.
@Anticimex
the interesting thing is when i upload the same sketch to the sensebender micro it works the AES Key will be stored correctly.
But on the Sensebender Gateway only the first two digits
@Anticimex
i checked the sketch already few times but i dont see an error.
here is the code i have only change my key with XX
