BLE advertising stoped un expectedly

[Dinkar]

Hello support,

We are developing a battery-operated sensor. For that, we are using nrf5340. Also, we made an enclosure for the sensor.

While developing we found that the BLE has stopped advertising.

Case 1: During further debugging found that when we keep the sensor open(without enclosure) it is advertising.

Case 2: If I keep the sensor in the enclosure and keep the charger connected to the sensor. After some time (approximately 2-3 hours) advertising is stopped. As the charger is connected to the sensor the sensor is minor heat(not extremely heat). I feel that due to heat, the sensor stopped advertising. Or is there any other reason for this issue? (This is only my observation there may be other reasons for causing the issue.).

Can anyone help me solve this advertising issue?

Appreciate your help.

Thanks,

Dinkar

Does it always work when it is outside of the enclosure? even for 2-3 hours?

Case 2: If I keep the sensor in the enclosure and keep the charger connected to the sensor. After some time (approximately 2-3 hours) advertising is stopped. As the charger is connected to the sensor the sensor is minor heat(not extremely heat). I feel that due to heat, the sensor stopped advertising. Or is there any other reason for this issue?

Does a reset solve the issue ? 
Have you tested to heat the device up while not in enclosure to see if same problem happens?



Can you share the schematic and maybe explain how the device is put together, what is the enclosure made out of? What other things are in the enclosure? what sensor?
