@selea hehe, snart. TÀnkt lÀgga det hÀr pÄ github sÄ andra kan fÄ nytta av det. Kanske göra nÄgot blogpost eller nÄt sen
@selea just nu oklart, har inte haft problem att jag behövde ladda den separat. Den sitter pÄ 90% hela tiden, jag tror pga begrÀnsning av laddning sÄ den laddar inte mer Àn 90% utan bara sitter dÀr, men som lÀgst den var ner pÄ 85% och sen tillbaka till 90
So now, when I have my #meshcore ESP32 bridge for SenseCAP POC working as it should, it was time to tackle the ESP32 power hunger issue that also @selea pointed out.
As I can't run deep sleep, and even light sleep behaves almost the same, killing Wi-Fi, etc. I did the next best thing. Downclocked CPU freq to 80MHz and lowered chatter to the bare minimum.
This resulted in 4-5x improvements directly.
Here are some pictures before and after, but before ESP32 was sitting around 0.1-0.2A and CPU was around 60-65C. After the fixes, the CPU is under 50C, and power draw is between 0.035 and 0.042A. I am happy with this, so I will run it outside for some time to see how it works.
@selea for now this is POC, will play a bit more with deep sleep, or if needed replace it with something else if this is not working good enough. With those pins exposed as RX and TX UART, you can connect whatever you want to it, as long as it has small format and can fit the case. Need also to see how much solar will help here when both devices are working together.
@pemensik I think that it could work too, but you still need to have something that will act as a MQTT bridge and I want to have this mounted outside self contained and self powered. The requirement that I had was that I would need to modify it so that if possible, I don't need any external connected device to it to work, which is why I did it this way :) @selea
