My favourite prototyping development board is Arduino Uno and Nodemcu #ArduinoUyir:fire: Because with these 2 board we can do most projects. Single Analog pin is the only problem with Nodemcu. That can be resolved by any other basic Arduino family development board. Both these two boards I fall in love:heart: with hardware. Nodemcu's WiFi+Uno's digital/analog pins. Also using these two a begginer can learn almost everything in hardware.

What the situation while your micro-controller confused in an infinity loop😖. Is there any case like hang or stuck your micro-controller while performing a task😖. What are the normal troubleshooting method? Reset Button, Right? Is it practically possible to do press on a button all time ?😕. So, What about a device to do this task ? sounds good. Cool...!🙂

@mhmdrameez I used that library before 6 Month ago and Worked fine. But now, it's not working. I think there are some issues with the library. Because there are somany open issues in GitHub Repo.

But while trying with Firebase ESP8299 Client library, which is listed on Arduino library manager it's worked fine for me. So, make a try using this library.

Library: Tools >> Manage Library > search for firebase esp8266

My output :

Firebase:

@salmanfaris forgot to call function getAcData() and getGyData() before goo.AcX... :joy:

Is there any commercial product which powered by ATMEGA328P with Arduino bootloader? Also, Is there any problem to use micro-controller in commercial products which using Arduino sketch?

Update!!
I found the issue
I created a Queue inside Rgpio.cpp and called a Funciton from main.cpp to check data in Queue. That worked well!!

24 Hours of Presentations, Workshops, Demos, and Exhibits Across All Time Zones

Across the world, makers have responded to shortages of medical supplies and equipment with agile designs, adaptive distributed manufacturing, and community organizing. Virtually Maker Faire will be a stage to share the projects and learn from the people behind this extraordinary civic response.

Virtually Maker Faire will take place online through video sessions and an exhibit showcase on Make: Projects

Virtually Maker Faire Tracks

Community Organizing

• The organization of local distribution networks for pickup and delivery.
• Tools and methods used to manage volunteers and incoming requests.
• Creating awareness in government, industry and citizens; Funding models or lack thereof.

Learning and Teaching

• How are maker educators adapting to digital tools.
• Encouraging hands-on learning at home.
• Doing hands-on workshops and courses online.
• How to train more people to participate in the civic response.

Re-thinking the Future

• How the pandemic and our response to it is teaching us to think differently.
• How, where and why we do things.
• Sustainability. Food. Well-being.

Design & Production

• The development, rapid prototyping, testing, and deployment of shared * solutions. Specific projects and how they developed.
• How capacity to produce locally matters to the response.
• Iterating to meet needs and respond to feedback from health care work.

Making

• Necessity of DIY.
• Making for fun.
• To keep one’s sanity.
• Social connections.

If you’ve been involved in the civic response for COVID-19, we want to hear from you! Tell us about your projects, share what’s going on in your community, tell us how your makerspace, FabLab, maker club or school is involved. Your stories and insight can help others. Get involved by organizing or leading a panel discussion, host a workshop or demonstration, share a presentation, or contribute a project.

I was trying to configure AP mode in Raspberrypi by using Network Manager. I'm using the below script. but it is throwing some errors.

I was trying to pass a pointer. That was the issue.

Update!!
I found the issue
I created a Queue inside Rgpio.cpp and called a Funciton from main.cpp to check data in Queue. That worked well!!

Reference to the #commit .

I'm trying to pass a value into Queue from Interrupt Service Routine(ISR) using xQueueSendFromISR() <-- Reference

But I'm getting this error and ESP restart immediately.

Guru Meditation Error: Core  0 panic'ed (LoadProhibited). Exception was unhandled.
Core 0 register dump:
PC      : 0x4021227c  PS      : 0x00000033  A0      : 0x4021c72e  A1      : 0x3ffe8220

Here is the gpio interrupt example which I'm following.

Here is my code. I did some modification in this.

Check 70th line of this location.

static void main_power_isr_handler(void* arg)
{
    xQueueHandle* main_q = (xQueueHandle*)arg;
    static main_q_payload_t msg;
    msg.hdr = E_MAIN_MSG_MAIN_POWER_STATUS;
    msg.bool_payload = gpio_get_level(GPIO_MAIN_POWER);
    //ets_printf("Someone Interrupted \n ");
    xQueueSendFromISR(main_q, &msg, NULL); //!!! THIS LINE
}

Thank-you @salmanfaris
It's solved.
Actually, It was my mistake. I didn't add a proper reset for MCU.

@salmanfaris Yes.

@salmanfaris When connecting with PC. It will work well.

@salmanfaris At that time not receiving an actual message. Receiving a blank message.

@salmanfaris Yes. I'm providing common ground. Resistors also working.

@salmanfaris
Sorry, leave that part
Actually I was using ("AT+CMGS=\"" +number+ "\""); this part and passing number into the funciton. This different functions all are done part of debugging.:grinning: just checking Is there any problem in string handling.
