3. Poor Signal range from sensor to gateway

Poor Signal range from sensor to gateway

  • cleight

    I am hoping someone here could possibly shed some insight as to what steps to take next. I am having issues getting a sensor that is approximately 15ft (3m) from the gateway to communicate. It appears it will not communicate with the gateway unless it is approximately 3ft (1m) away from the gateway. Here is some background of my environment:

    Gateway:
    itead studio iBoard
    NRF24L01+ (Added 4.7u Decoupling Capacitor, didn't make a difference)
    Version 1.5
    Sketch:

    I have changed the wireless channel to 120, this didn't make any difference. I have also increased the power levels in myconfig.h to the following:

    #define RF24_PA_LEVEL 	   RF24_PA_MAX
#define RF24_PA_LEVEL_GW   RF24_PA_MAX

    Didn't help so I then changed them to:

    #define RF24_PA_LEVEL 	   RF24_PA_HIGH
#define RF24_PA_LEVEL_GW   RF24_PA_HIGH

    At this point I am not sure what to try. The sensor is inside of my Hot Tub Cabinet, doesn't have any metal around it but the signal does need to go around or through the 400 gallons of water.

    Since no one has posted anything in the form of suggestions. I am going to order a NRF24L01+PA+LNA for my gateway and see if it helps. I built a simple temp/humidity sensor from the examples and have it directly 1 floor above the gateway and it isn't being picked up by the gateway either. The power supply going to my iBoard gateway is a 9V 1000ma wall wart, I believe this has plenty of power to run the Ardunio, Ethernet, and the radio. I have also switched the 4.7uf capacitor for a 47uf capacitor without luck either.

    As you said, you tried the cap but for me its usually a power problem.
    Sometimes it is the sensor connected that draws to much power or makes the radio behave like this.
    Also sometimes its a bad radio.

    I would try to hook up the radio and arduino only (no sensors) and connect it to a different power supply and see if that makes any differnce.

    From what I read, 2.4Ghz travels extremely bad through water.

    So my only options are a lp radio with an extension cable /antenna outside the hot tub cabinet or possibly the rm69 radio correct?

    Would it be possible to hard wire the sensor via ether net to the mysen sort network?

    Do you know what the converter on your board delivers? The 700mA from your wall wart may be fine but maybe the 9 to 3.3v converter on the board don't deliver enough current?
    Any signal will populate bad through water but normally it would "find" a way around that by reflections etc.

    I recieved my NRF24L01+PA+LNA yesterday in the mail. I installed this on my gateway and still the range is exactly how it was to my sensors. I have built another simple temp/humidity sensor that is only 10' from the gateway and still cannot communicate to the gateway. I still have RF24_PA_MAX for both the sensors and the gateway and nothing.

    I am now at the point of wondering if I have a bad iBoard (gateway) that is causing these issues. Any more insight before I order another iBoard for a gateway?

    Also if I wanted to temporarily change from an ethernet gateway to a serial/usb gateway with Vera what all would be involved?

    Good news! I was able to get everything working finally! Here it must of been an issue with my gateway sketch along with changing power settings on the gateway to RF24_PA_LOW. my only issue now with my gateway is Vera shows it constantly in inclusion mode, I believe it has something to do with my sketch, I don't have an inclusion button on my iBoard Gateway so I changed the PIN in the sketch to a fictitious pin but that seems to have just compounded the issue, if anyone can point me in the right direction on that front it would be much appreciated.
