Solved the problem “RH_RF95 Does not name a type”

Solved the problem “RH_95 Does not name a type”

The Developers or users may face a problem when they follow the step of the user manual try to Upload a sketch to the Dragino Lora gateway LG01-S or Upload Sketch to Lora shield board by using the newest version Arduino-1.8.5. the compiler will show: class RH_RF95′ has no member named ‘setSpreadingFactor’ or RH_RF95 Does not name a type.

You may try many ways or search on the internet to find a way to solve the problems when the problems come.i have faced this problem and solved the problems successfully.
Here are my way and explanation:
1. The explanation
you may had used the old version Lora Library before like the version RadioHead-1.63 and add to the IDE as one library now the Dragino had been upgraded the newest version Lora library which is RadioHead-master the problems comes from the conflict between the old version and newest version Lora library(The newest version Lora library can be download from https://github.com/dragino/RadioHead/archive/master.zip).
2. The way solved the problems
1) find the library file and delete the RadioHead file here is the route(you cant uninstall from the Library Manager)

C:\Users\Administrator\Documents\Arduino\libraries/RadioHead
2)find the cached file and delete the Arduino15 file here is the route(which will store the history data for the old version library)

C:\Users\Administrator\AppData\Local\Arduino15
3) Install the newest version Lora Library by using the Library Manager again.
Then problem solved you can try it again.

Funding Support for Prototypes Service

Service

Good ideas are just like a The fleeting meteors in the sky how can we catch it and make it comes to real world? Idea worth express.Funding Support for Prototypes Service target the electronic world.If you have a good idea just let us know we will help you to design and make it comes to truth only if we also think it’s good or you can approve it’s good,If you already have finished a design just let us know we can help you to make prototype for free only if we think it can get people educated or bring the benefit to people’s life or work.

Possibility

Our team set at the City Shenzhen,Guangdong,China where has the largest electronics market which name is HUAQIANGBEI You can find anything electronic parts here within five minutes at a small counter which spread over the market.Here it also has a full mature supply chain,we can gurantee that we can offer an professional,Experienced and fast service.

Implementation

We are going to fully use the social network media to get further exposure to our service. Funding Support for Prototypes Group at Facebook, Funding Support for Prototypes at the communities of google+, instructables project.We have online store which is Dwmzone whih will help to sell the prototypes.we have a Venture capital team who is going to funding for the prototypes,We have a experienced engineers team who is going to offer a profesional consultant service for the coming ideas and design.We also have has a supply chain manager team who is going to gurantee a fast manufacture and delivery service.

Process

dwmzone-Value-your-ideas-and-random-design-Royalty

Let me explain the whole process simply.

Ownership

Lessors own the ideas and designs Dwmzone will rent the ideas or designs In a certain period of time(one or three years) after that the Dwmzone will release the ownership back to the Lessors.

Division of labour

Lessors

Turn the ideas and design into a Required PCB information and Required Bom information send to Dwmzone.Share the software to the End Users and Shoot a video give an introduction about the design and ideas and guide the End Users how to use it.reply the comments and answer the questions.

Dwmzone

Give lessors a professional consultancy make it more practicable and turn the ideas and design to a real products,Sign a Tenancy agreement with Lessors which will write down the lease period and Percentage for paid royalty (we will pay you a percentage-based royalty per product sold), Offer a vc funding and charge the manufacture ,stock,delivery and sell around the word.

Endusers

Pay for the service, got the benefit and fun.

RFduino Board User Manule

Leave a reply

RFduino Board User Manule

RFduino Board which is compatible with Arduino UNO R3 and Arduino IDE. We recommand you use the Source Arduino 1.0.5 as IDE.

RFduino Board which also name HopeDuino But we used to call it as RFduino board.If there are any questions please contact us sales@odlstore.com. We will give more details about the name.

1.Prepare Hardware and software:

RFduino board
Arduino IDE 1.0.5 version
Silabs CP2102 driver package
HoepRF-HSP hardware and softare service package(Click and download directly)
USB cable (A mouth turn B)

2.Installation

1.) Arduino IDE installation
Download the Arduino 1.0.5 package extract directly to need to put the path, this version is free of installation.As shown in the figure below:

2.) CP2102 chip driver installation

Download “CP210x_VCP_Windows” decompression, in computer system, according to you choose a 64 – bit or 32-bit drivers, double-click the install.As shown in the figure below:

3.) Installation HoepRF-HSP hardware and softare service package(Click and download directly).

Download the “HoepRF-HSP“hardware and softare service package decompression,you can find two folders “hardware” and “libraries”, Copy the Files under those two folders to the Arduino 1.0.5 “hardware” and “libraries” folders which has the same name.As shown in the figure below:

Copy the content of the “hardware” in HoepRF-HSP to the file Arduino 1.0.5 “hardware”.

Copy the content of the “libraries” in HoepRF-HSP to the file Arduino 1.0.5 “libraries”.

4.) Connect the RFduino board to PC through the serial port.

Double-click the arduino. Exe “to open the arduino IDE interface, the interface of select [ToolS] -> [ Board] -> [Larduino core w/LGT8f328d ], as shown in the figure below:

dwmzone-Connect-the-RFduino-board-PC-port

After connect two board you will see as below:

dwmzone-Connect-the-RFduino-2-board-PC-port

3. Arduino IDE Setting

Double-click the arduino. Exe “to open the arduino IDE interface, the interface of select [Tools] – >[Board] – >[Larduino core w/LGT8f328d 】, as shown in the figure below:

4. Test LED Blink

After we finished the IDE setting the we can run a test to make sure thoes board works:

Select [file] – > [example] ->[01. Basics] -> “Blink”, as shown in the figure below:

At this time will re-open the Blink routine file, as shown in the figure below, click on “compile and download”.

After compiling finished and download software to RFduino board, after the download is complete, the red LED (L13) will according to the interval of 1 second, Means download success, Shows as the following figure:

dwmzone-Arduino-IDE-Setting-LED-Blinking

5.Ending

You can continue and Enjoy all of the series wireles modules Function which various corresponding validation HopeRF routines for you need to test.
