Reference Design of nRF51822 for 1 meter range minimum

I need a reference design of nRF51822 for minimum 1 meter range . The circuit will run from CR2032 battery for at least 24 hours and will take some readings from ADC input and sends these data to another similar circuit . The receiver circuit always waits for incoming data and when ADC values will cross threshold limit then it will send data to receiver and receiver will execute corresponding commands . The sensors will run through external power supply , nRF51822 circuit will just read the data and will transmit or receive and communicate among them .

The casing of the receiver will be made of 3mm thick Acrylic Sheet and will be fully airtight , the pcb will be put inside the casing , the casing will be hollow type .

Please help me by providing a reference design which will meet these requirements , any idea , concept correction will be highly appreciated . Thanks in advance .

  • You can add the data to the advertisement package and just liesten for them. Or you can get the two devices into connected mode where battery powered sensor is in connceted mode. It can use the S110 stack, Doing just advertisement with the sensor it will run the MSU of 30uS + the ADC but in connected mode should comsume somthing between 0,3 and 4 mA. Still no problem running from the CR2032 battery. In connected mode the data can be encrypted but in advertisement everyone can listen in on the data. Depending on how you want the application to run. Power consuption of the listener till probably be around 13mA.

    If you have a sample of the casing ( without any metal ) you can put it in the microwave and see if the mircowave heats up the plastic. If the plastic gets hot/warm then the casing is not siuted for this application.
