I'm making a wearable device using a vroom 32 and the arduino framework.
I would like to ask some questions about the board but I'm a web developer and I don't have too much knowledge of the mcu jargon so many thing may slip my understanding, so please in your answers, if able tell me what keyword should I look for.
- I can see that even when I have the wifi and bluetooth turned off that the module is getting hot. I have two considerations about this. First of, the device I'm making is going to be wearable and I think that it could potentially cause some discomfort. Secondly, as the device is going to be powered with a LiPo battery, I fear that it could become somewhat dangerous. Now, I've read on the esp32 datasheet that the processor can be used in 2MHz frequency (I suppose the heat is dissipated due the fast nature of the processor) is this really possible? Should it make some difference?
- I want the device, when it is "turned on" to record some events with timestamps. For that I plan to check the time with my phone via the bluetooth and an app. When the device has been used for the spell of time the user needs it, it should fall into sleep mode. Can I keep track of the time when in sleep mode?
- Can I store data to the device (on normal, not sleep mode), along with the timestamps, so I can request them later via bluetooth?
Thank you!
