@korttoma, thanks for the advice. Now I understand better. I guess I will need to come up with version 2 for my gateway.
I did go through the articles shared by @sundberg84 but it is too much reading for me. I find it hard for me to understand them base on my level of knowledge. Your summary helps me a lot.

I see one potential problem with your GW. You are powering the NRF24L01+ PA LNA radio directly from the arduino 3.3V pin.
Be aware that the 3.3V pin on the arduino can not feed enough current for this kind of radio module if you use it at full power.
If you use the default RF24_PA_LEVEL_GW = RF24_PA_LOW it might work.
thanks for your advice. i didn't know it is a problem because it still works. I just follow the instruction in https://www.mysensors.org/build/connect_radio . The video https://youtu.be/TBvGrB094Co also shows that the radio is connected directly to 3.3V pin. If you don't power the radio directly from the 3.3V pin, may I know how do you power it? I am sorry, I am totally new to this.

Yes each time you upload a sketch it replaces the one that is already there.
Thanks.

Here you have a sample of one of my battery nodes. Now I'm using V2.0 of Library, but this used to work before updating
Thanks.
There is also another thing concern me. What if my neighbor also into Mysensors? Will he be able to view all the data from my sensors? How do I secure the nodes?
@mfalkvidd thanks.
I manage to build a couple of sensors powered by 2 AA batteries.
However I'm stuck at monitoring the battery level.
After I uploaded BatteryPoweredSensor.ino to my board, it overwrote the sensor sketch I uploaded earlier.
Do I have to merge both sketches into one before upload?
Hi,
I just started on mysensors and I have zero knowledge in electronics.
I want to create some sensor nodes using arduino pro mini.
However i have few doubts. Hope someone can help a newbie.
I can see only one VCC pin (excluding the one on programming header which i would like keep it for uploading sketches in future). How do I connect my radio and sensor? Shouldn't it be at least 2 VCC pins? Or can I fit in 2 wires into the same VCC pin?
I'm powering the sensor node with 2 AA batteries. The negative terminal goes to ground. What about the positive terminal? Does is goes to RAW?
I'm sorry for the silly questions.

If you have an Uno around your can use that for programming the ProMini.

It's weekend and I finally have the time to give this another chance and guess what? It works! I manage to upload the sketch to my Pro Mini and successfully created my first ever MySensors sensor! Thank you so much for that!

Thank you very much! Now time to dig out my old spare Uno.

I would just order from some place(s) else and hope to get a working adapter. I have ordered 5 and all of them work on my Win7 machine. You could also try the CH340 chip.
Thanks. May I know where did you buy them from? CH340 chip? Also from FTDI?

What I've done is to buy some of these pretty USB/Serial adapters, from tindie
https://www.tindie.com/products/ddebeer/usb-to-serial--uart-5v-or-33v-695-/
Thanks. But after add shipping, I feel it is not worth it compare to get a new Uno from the nearest electronic shop.

unless your windows 7 PC was very behind on updates and you just happen to have the flaked driver.
My Windows is auto updating itself and I don't think it is a flaked driver cause I have installed multiple versions of the drivers.
I am facing the same problem. I purchased my FTDI FT232RL from http://www.ebay.com/itm/-/111864322684
When I plugged it into my Windows 7 PC, it pops up this error...
In my device manager, I sees Unknown Device under Universal Serial Bus Controllers...
I have tried update the drivers using various versions such as...
All still give me the same error.
When I use a tool called USBView downloaded from http://www.ftdichip.com/Support/Utilities.htm#MicrosoftUSBView , it shows me...
Both idVendor and idProduct are 0x0000
Then I use MProg 3.5 downloaded from http://www.ftdichip.com/Support/Utilities.htm#MProg . After I press scan, it says...
Number Of Blank Devices = 0
Number Of Programmed Devices = 0
I have wasted a lot of time to get this working. I really don't want to replace my unit with the same thing as I afraid the same problem will happen again. I am wondering is there any other ways to upload the sketches to my Arduino Pro Mini?
@C4Vette thanks! I can see more details is at http://www.mysensors.org/build/advanced_gateway
