Moto: Need to check the location of the card in zones with a long battery life of 2 years
Design idea:
Nordic nrf52 + key1 + Led (low power) + MCU chip (ultra-low power) + 2 x CR3032
Purpose:
Need to make a broadcaster with the following parameters
macid,uuid,temp,rssi,key_state, datetime
Note: If the key is press long for 3 sec it will change a bit of key_state to 1 else show 0
Settings:
Read DateTime from phone/uart and update rtc
The set time interval of broadcast (default time interval is 1sec)
Set UUID
Set Sleep time will be set (say if time is set 07:00 14:00 then it should transmit between those interval other hours it should sleep)
Requirement:
Sch files
Gerber files
BOM
Firmware development
App to show the above data is got at receiving end
Hello sir,
I have experience in designing electronics circuits and can develop hardware compatible smartphone and PC based apps.
I also have done a lot of IoT projects and can transform your idea into a fully working product.
If you wish we can discuss details in chat.
Thanks
Hi,
I hope you are doing well. I have extensive experience in BLE based embedded projects using NRF51 and NRF52 module.
I have understood your requirements and I can execute it in less possible time.
Looking Forward,
Khawaja
