BLOG 15 : BLE Subsystem

Posted by gsgill112 Nov 13, 2017
Hey guys, Let dive into the BLE Sub Section. I was not able to implement much on this front but it is not very difficult to implement. Let me go through the basics first   What is BLE ?? BLE Stands for Bluetooth Low Energy. It is a Simple yet Powerful Technology specially designed for Low power Applications. It's Strength lies in the STATE information transmission.   So, You may ask STATE information ?? Well that means something like Is the Device ON or OFF, is the fan ON or OFF wha ...
Ok, In this Blog I will talk about implementation of the Sensor Subsystem in My project.   Firstly the Role of Sensor Subsystem was to identify the weather for ride and to send it to the User. I had Dropped the Idea of pothole detection as it was not a worth Idea, moreover In my Nextion display You could just touch to report the pothole. see the BUMP Button below !!   As there was a mBed Library available online HERE as well as an Example Program available HERE it was easy to get ...
PREVIOUS BLOG During the testing of the assembly which held fine I met with a Accident on my cycle Damn those Disk Breaks . I have got More, but I am avoiding uploading due to the content of the images   As humiliating it would sound Nothing much happened to the stm32 but the Nextion Display got damages and I myself got a bit damaged   As I mentioned that I have limited time for Project. As of Now its 20 OCT 2017 and I have to move to a remote location. I won't be able to ...
Hey guys Lets now decide how to plus this Cable mess on my Bike   I am a poor Man without any support of a 3D Printer or something fancy, But I am a huge fan of Recycled or Found objects So in a nearby Glass shop I found a piece of broken Acrylic Sheet laying around and the guy was ok if I took It so I took it happily After marking the holders for STM32 on the acrylic I stripped the acrylic to the required dimensions and marked the board mounting holes. (I am not sure why STM s ...

Hey Guys, another SHORT UPDATE , I have somehow managed to get the button interrupts working yayyyyy with the BLE Code So now I can go further   Here is a video demonstrating updation of Nextion display based on the Hall Sensor Data and some Computations.     Code Snippets 1. Define Global Timer Object           Timer tick; 2. in Main()         stopC = 1;      ...
Hey Guys, While working on the Battery decisions in my previous Blog I came across a huge issue of power consumption.   Let's see how - taking into consideration the following 1.     Avg Current consumption - ~15mA for the STM32 Nucleo and ~105mA for the Display (Considering 15mA to be insignificant) 2.     So with a 3000mAH battery and about 110mA load  Running time = 3000/110 * 0.7. == ~19 Hours 3.     Now if somehow ...
Hey guys welcome to another IoTonWheels design challenge blog of project SbSr. Lets talk about powering my project at this stage and learn more about various approaches I followed and issues I faced   So the first challenge was to finalise a power source, obviously the battery, and to fix that lets first find out the power requirement of the system. Luckily there is a IDD measurement jumper int the STM32 Nucleo Board which will give us a good estimate of the power consumed by the STM32 Ha ...
Hey guys, Here is an another update on sending dummy sensor value and outputting the data to the Nextion Display.   SEE THE VIDEO   SENDING DATA TO NEXTION DISPLAY So, How do one send data to sexton display using STM32,   Lets go through the Nextion instruction set where we will se that in  the display there are concepts of Objects such as text object, button object , etc. each of the objects have certain properties like colour, text, value, etc ... .. so the way we ...
Hey Guys Welcome to yet another Very Short UPDATE Blog Post on Smart Bike Smart Rider Project for IoTonWheels Design Challenge. In this Blog Post I will Go through testing and setting up the Hall effect Sensor With the STM32 Board using mBed Toolchain.   So in the last post we had fabricated our sensor board Now lets interface it In this image Pin one on Top is the Vcc (+3.3V), Middle is GND and Bottom is Vo (i.e Signal pin) So the sensor by defaults Outputs a High i.e. Logic 1 when no ...
First of All, Another pic of my photography skills Ok, after admiring the golden sand, lets come to the point. In my previous Blog I had mentioned about Hall effect sensor and how I have tested the design and finalised it for my project.   In this blog I will walk through the process of getting a more permanent prototype to play with. So, lets get started with the Easiest way to Homemake PCB's of What I would like to call the Poor Artist's way of PCB Prototyping   Now you may ...
Hello Guys Another pic of my Photography Skills   Ok, So coming on to the topic.   Homemade Smart Cycle Computer - Finalising Sensor's and INTERFACE So, A Part of the project was to get a System of measuring the Speed, Distance travelled, Avg Speed, etc. In this blog I will review various mechanisms I tried and Which one worked the best   OK, Many of us are used to the Cycle computers the small little thing that tells us some important Information like The Speed, Dista ...
  PREVIOUS BLOG   NEXT BLOG   Hello everyone, Sorry for delay in blogs, I was in transit and I am currently located HERE So It Kinna difficult to stay connected to the world. Moving on, as the part of the Challengers Kit we received the following Hardware,                                               But first lets go through the Unboxing Video sorry for ...
