Hello:
According to the website, please nrf52832 circuit design, without adding other peripherals, just as a radio Beacon, button battery voltage at 2.3 V nrf52832 cannot work, cannot reach 1.7 V chip performance minimum working voltage is what reason?How?
Hi,
To which website are you referring? The minimum operating voltage of the nRF52832 is 1.7 V, and there are no limitations on what it can do at that voltage. The nRF does not care about the voltage as long as it is within the supported range, 1.7 V - 3.6 V.
However, it is the voltage seen by the nRF that is important. If you meassure a battery you will see that the voltage drops as the current drawn from it increases. This is even more so if the battery is close to being depleted. This means that you cannot take a almost discharged coin cell battery where you meassure a voltage of just above 1.7 V and expect it to work, as the voltage will probably drop below 1.7 V whenever the nRF draws a significant current (e.g when the CPU or radio is active). This will cause a brownout reset in the nRF.
Hello:
Thank you very much for taking time out of Einar busy schedule to help me solve my confusion. My hardware circuit USES the circuit design in the official nrf52832_ps_vv.3.Now the power consumption is on my side I use a new button battery radio Beacon interval under the condition of 300 ms power 0 DBM can only be used for 15 days, the power consumption is so great in what could be the cause, what measures can reduce the power consumption of it?
Hi,
I cannot say anything about the reason for the current consumption in your case without more information, but I have a few questions that might shed some light on it:
You may also find some useful advice and hits in the Optimizing Power on nRF52 Designs blog post.
Hello,
Thank you very much for the power consumption optimization Suggestions you proposed and recommended, which are very useful to me. I will continue to optimize the driver version according to the optimization Suggestions!
