Did anybody tested this board with an ATSHA204A on A2? The ATSHA204A works with 2.0 to 5.5 V.

@Mikael-Kermorgant I'm using fhem. It is possible, that I can set an offline state after 20sec with fhem. I will try this.

Hello,
I've successfuly uploaded these sketch to my Atmega328p. It works fine. Two things I want add:

• I have changed the speed in the file MyConfig_h -> #define BAUD_RATE 9600 (otherwise I got nothing at the serial output)
• The sensor sends an 1 on "motion". How can I send an 0 on "no Motion" after 20sec? (low on data pin?)

Thank you

@bjacobse Which Optiboot loader did you exactly use? I can try it. I have an Arduino Pro Mini.

@bjacobse I'm out of fucus. What was the problem? Can you burn the bootloader+sketch with an USBtiny on an bare Atmgea328p? Connected on MISO/MOSI/SCK/RESET/VCC/GND?
The Arduino Pro Mini is different from the Atmgea328p. On the arduino is an external clock.

@bjacobse I thought the USBtiny is only to upload the bootloader, not the mysensors software.
I did two things:

1. Burn the bootloader atmega328_1a.hex to an bare Atmega328p with an Arduino as ISP
2. Upload an simple scetch to the Atmega with an RX/TX uploader (I used an USB to TTL with an FTDI and also an Ardunino Uno without the Atmega chip, like here http://forum.mysensors.org/uploads/files/1454449901412-7.png) Both are working.

I'm still waiting for the PCB. After receiving I want to build the motion sensor.

@bjacobse Witch bootloader you have taken?

@m26872 Sure, but not with an bootloader (optiboot with intenal clock) on an bare Atmega. Later I will try this: http://forum.mysensors.org/uploads/files/1454449901412-7.png
I build some MySensors with an Arduino Micro, but not with only an Atmega.

Update: I don't know what's different, but this works. Perhaps I forget to connect Reset from FDL -> Pin 1.
Now I can upload simple sketches.

@bjacobse No, used the bootloader from here (http://forum.mysensors.org/uploads/files/1443392692398-atmega328_1a.hex). This is an bootloader for the internal clock.
Baud settings to upload the sketch or the bootloader?

Hello,
I have problems to upload the scatch to the bare Amtel. I use an USB-TTL FTL Adaper and connect, RX/TX and Reset Pin with 100n->DTR. But I got always errors on uploading.

The bootloader I have successfull burned with an raspberry pi and gpio (http://www.lxccu.com/hb-raspberry-bootloader-update):

sudo bin/avrdude -Cbin/avrdude.conf -p m328p -P gpio -c gpio -U lfuse:w:0x62:m -U hfuse:w:0xde:m -U efuse:w:0x07:m -U lock:w:0x2F:m -e -Uflash:w:1443392692398-atmega328_1a.hex:i
avrdude: safemode: Fuses OK

How can I got it working?
Thank you

Hello, i have Problems to compile MySensors Serial Gateway with the latest Adruino IDE 1.6.7 and the development Version from MySensors. There is no USBDevice.init() anymore. I disabled the call in MyMainDefault.cpp and it compiles an works fine. Is this an workaround?

I got also problems to upload the scetch to an arduino micro. After uploading the micro does not connect on any COM-Port. Only if I reset the bootloader, I can write other sample scetches to the micro. So it seams, that the gateway code does not working well with an arduino micro.

I'm also interested on your PCB board design. Can you share it? Thank you.
