I have to make project to notify parents if baby left inside the car. i will installed 1sheeld inside child car seat, and when parents leave the car ( outside specific range) with their smartphone and they forgot to take their child, 1 sheeld will notify parents that their child still inside the car.
but i have 1 more question, the proximity only change from 0.0cm to 1.0cm only even though i move my phone farther.
hi eslam. i think i have figured out the problem. the proximity sensor in my smartphone in the front, so when i move the phone outside range proximity didnt work because 1sheeld cant read the proximity sensor from back of phone. when i place front phone to 1 sheeld, the proximity work and i have received the notification and message.
I did receive the notification from 1sheeld, but 1 time only, and sometime i didnt receive notification at all. i already insert +(my number) but its also didnt work. what i realise is when i try the getting started tutorial, we give some noise to mic at smartphone and led(output) is blinking, thats mean its works right? but when use proximity to send message(output) or other notification its didnt work.
hi eslam. i’m finish debugging. i have done the mic tutorial and it work. the led on when i make some noise but when i do the proximity example it still didnt work properly. i only receive 1 message when phone outside range and proximity change to 1.0cm for awhile. thats all. whats confusing me is txd and rxd led keep blinking faster but no sms receive. is my 1sheeld have problem? or my smartphone ? thanks in advance for the reply!
i have try the coding u give but it doesnt work at all. but TXD and RXD led keep blinking means 1sheeld keep transmit and receive data right? but my smartphone didnt receive any sms or notification at all.
