Hi dear
According to the datasheet, the operating temperature range of this chip is only -40~85°.
We are now doing a high temperature（70°） experiment and found that Bluetooth cannot normally operate.
I don’t know if it is caused by excessive ambient temperature range. Once it has returned to normal temperature, it can recover normal operation.
What signals should be confirm at high temperature to determine whether it is caused by over ambient temperature 85°?
In addition, the chip will stop working once the ambient temperature exceeds 85℃， What are the characteristics that it shutdown to stop working?
what need i do ?
thanks
hejun
