@gohan for me version dev (2.2)

@Richard-van-der-Plas

Same trouble for me. I use mySensors since 2 years and I have no problem with my Arduino Gateway. But from now 2 weeks, I try to use a pi gateway. It's working well but sometime, don't no why, my nrf24 stop to receive messages. Just restarting mygw service and re-work again. I don't see nothing anormal in my log, stop randomlly after 1 or 2 days.

Maybe a power issue to nrf24, I will try to add capacitor just for testing if can resolve this problem.

@GertSanders Thanks... after practice and practice and practice again... I have now 4 narrow board working with si7021 sensor... I need to put my solder tip very high and use alot of flux..

@GertSanders Yes I used the version 1.1 and yes I connect the jumper pad correctly.

After some hard test, I found the problem, is it my solder or a bad batch of SMD NRF24L01 I explain my problem, I make a good solder of the SMD NRF24L01, I put power on the board for testing it and is it working for 2-3 loop because I open the led (d6) on each loop. After 2-3 loop the board is freezing. After I check again the solder and some pin of the SMD NRF24L01+ is shorted (check with my multi-meter). I can explain why, is it my skill of soldering or a bad batch of SMD NRF24lL01+. I test with 5 different and always the same, after power it.. it will shorted some pin. I make my order on this ebay store: http://www.ebay.ca/itm/401054727893?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT

@alexsh1 I use the this lib: https://github.com/LowPowerLab/SI7021 My board freeze when initialize with begin function.

I can't have the error exactly because this board don't have any FTDI connection. But the same atmega328p chip with other board, it's working !! I think again is it because the board use internal oscillator.

Hi, I have finally receive your narrow board.. I try with a Si7021 sensor (the GY-21 ebay version) and I have no success. But with your other board, because I have your 2 other board version (ac/dc board and the small battery one) it's working with no problem. The difference I think is the first board without external crystal. After reading in forum, I think with Slim board version, i'm not the first with this problem. Did you test your board with si7021 sensor, or can you give my a clue ?? Thanks

@GertSanders oh thanks, I have made an error... Maybe it will be working with MYSBootloader 1.3pre2 because he don't require any external memory.. Did you try before?

@GertSanders I have a couple of your board and I will be very happy. Now I will want to try the OTA feature with this board. Did you have DualOptiboot already compiled (hex file) with D8 led pin and with 8 mhz external crystal? It will be cool you include this file like Optiboot 6.2.. Thanks

After make some test this morning I found a solution but I do not know why and what is the difference.

I explain:

When I used this DHT librairies (https://github.com/markruys/arduino-DHT), this one come with mysensors librairies. I can read my DHT22 sensor with my FTDI cable but is not working with from a DC 5v in, reading always 0.

But If now I used this librairies (https://github.com/adafruit/DHT-sensor-library) , is working with FTDI cable and now with my DC 5v in.

@AWI Yes I have pull up !

I wrote D7 but in my sketch is D6

#define DHT_PIN 6

This is my board:

I don't want to use the bat jumber because my source is by USB plug (5v).

My question is why is it working when I plug with my FTDI Cable (5v version).

I will try tonight with other sensor like Si7021 but i'm pretty sure it will be working.

@GertSanders Can you give me a hint? I have 10 of this board and for one I want to use with external DC 5v. For this one, I put the AMS1117. All is working when I check with my meter, I have 3.3v for the NRF24 and 5v for the ATMEGA328P. Now when I use this board with DHT22 temp sensor (plug into D7), I check my scketch with FTDI cable and the Serial Monitor of Arduino IDE and all is working good. When I used with the external DC 5v, all the board working good except the DTH22, read 0 for temp and humidity but NRF24 work good. I try to figure what is the problem and I can't find any solution. My external DC is pluged into same terminals as the battery holders V+ and V-.

Thanks again and sorry for my skill of english, I'm french from Quebec, Canada.

@GertSanders , 1 question, you have specified 1/8w resistor... did you know if 1/4w fit on narrow board ?

@GertSanders I'm a fan of your boards. I have your 20x30mm board, AC/Capable 50x50mm board (my favorite) and now I ordered your v1.1 of your narrow board because you are agree my suggestion for I2C port with jumper

Your plan is it to change your narrow board with SDL/SDA pad. maybe a jumper to change D2/D3 pin to SDL/SDA?

Thanks for your clear explication! I have another question, where is the FTDI port ?

Hi GertSanders,

After ordered and make 3 of 50mm x 30mm board with success. Now I ordered the AC Capable 50mm x 50mm board. I try to read the schema and I have some question. If I want to use this board with only 2 AAA battery, Do I need to use AMS1117? and witch jumper do I need to close? It is optional to use AT24C ?

Thank you for your help

AAA holders

Like this? http://www.aliexpress.com/item/Wholesale-30Pcs-lot-1-AAA-Battery-Case-Holder-Box-Base-Socket-With-two-pins-AAA-Battery/32244035084.html?spm=2114.01020208.3.182.YlN1cu&ws_ab_test=searchweb201556_2_79_78_77_80,searchweb201644_0,searchweb201560_5

I order from OSHpark the v2 of your own board and I have a question, if I run it with 2AA battery for example, I put jumpers (marked red on the picture) and it is working.

But if I want to try with 5v input, like from usb charger, do I need to have a 3.3v regulator for the NRF24+ ? And if yes, do I need other pcb to complete this?

Other question, what is the use of the jumper J1? I'm not sure...

Thanks again !!

very good job, i'm very interested to try your board. Did you try to order from
dirtypcbs.com vs oshpark for the price?

It is normal when I connect my EthernetGateway with MYController, I saw connected in the log but after connecting, MYController not send any request for request gateway version? If a send any request with send buton, after that, now all is working because I recevice Gateway ready message.

This behavior is new for me after upgrading my EthernetGateway to Arduino 1.7 and My Sensors 1.5!

After some test I found what is new. I don't know why but this line:

EthernetClient newclient = server.available();

When the client is trying to connect, server.available() wait for client sent character before returning true (1). Is it new for Arduno 1.6?

Hi,

Since upgraded to version 1.5, I uploaded the new EthernetGateway for upgrade my Arduino Uno (with Ethernet shield) without any problem but now when I connect to my gateway, the client must be send a character before gateway recognize the client. After the client send a character, gateway debugger print Finishing and now the client receive all sensor message from gateway.

MYSController can' t connect to this new gateway because after he try to connect, is not sending any character to gateway.

It is new for version 1.5 because with version 1.4, it's working without this strange behavior.

Sorry for my english !
