Hello,

We are developing wristband without a screen so we are planning to have a 3.7V 500mAh battery on top, then PCB that will have CYBLE-0220001-00 module soldered, and on the same PCB on the bottom side there will be MAX30100 heart rate sensor.

So here my question is as I am planning to have CYBLE-0220001-00 BLE in between Battery and MAX30100 sensor module. I am worried about do I get the CYBLE-0220001-00 BLE (signal strength) range as usual? or it will drop due to battery-penetrating(battery material)(BLE signal cannot pass easily) of battery kept on top?

Please suggest an arrangement of CYBLE-0220001-00.

I am attaching a battery image for your reference. Click here

Thanks and regards,

Neeraj

Hope the above information helps you to decide the proper placement.

We strictly recommend you to place the components in place and test the range before going for prototype.

Thanks

Ganesh
