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.

IOT-Live Stock Management for Cattlle Farm

The parameters for the monitoring of cattle diseases are Dozens of diseases in cattle, but we know from the study that the body temperature, the daily activity, Feed intake behavior are very important parameters to indicate the diseases like BRD, FMD, Mastitis, Septicemia and etc for the Beef and Cows.and those parameters also can use to monitor the estrusdetection for Cows。

System Structure

Our research team follows those parameters to create a live Stock management system for farms. the basic structure of the system is sensor level, Communication level, Data analysis and present level.

Sensors level

We learn from some research, Monitoring body temperature, High sensitivity for BRD (>90%), Moderate-to-low specificity for BRD (≈50%).Monitoring physical activity, Moderate-to-low sensitivity for BRD (60%), Moderate specificity for BRD (≈70%). Monitoring feeding behavior, Moderate-to-low sensitivity for BRD (<70%).Moderate specificity for BRD (≈75%).None of the parameters alone can accurate to detect sick cattle. it needs a Combination of health parameters to balance the battle of the sensitivity and specificity monitoring of cattle sickness.we are using one tag to measure those three parameters.

Communication level

We are creating a Flexible, robust, reliable communication Network by wireless communication technology. we are using an IOT/Lora gateway to bridge Lora wireless network to an IP network base on WiFi, Ethernet, 3G or 4G cellular. we are using the Lora to FSK tag readers to extend the distance between the wireless tags to the IOT/Lora gateway, we are using the temperature sensors and accelerator sensor to monitor the cattle body temperature and daily activity we put a tag reader to a feed bunk to monitor the Duration and frequency of feeding the wireless tags are required up to 5 years battery life.The communication level is also a real-time location system network it’s for cattle real time track and real time inventory.

Data analysis and Present level

The Data analysis and present level are the most importance part because it will present the results and data to the end user- farmers which should be the information mean something to the farmers and Can be translated to a meaningful action. it will be user-friendly, Explains an underlying biological process and Information readily available to farmers.

Summary

We put the animal welfare as the top priority to tag design any wearable thing to the cattle should not add stress, uncomfortable and even hurt them.We will carefully to choice the materials of the tag and design a suitable tag easy the way to wear to a cattle. for the farm, the system should be user-friendly and can translate information into a meaningful action.Low-cost for a unit and it should be less USD100 investment per cattle.
