Esp32: ADV(adv_interval = 1000.0ms) average current 2.55mA
nRF52810: (Interval 805.00 ms) average current 9.3 µA

Only a factor of 275. It seems like it should be possible to do a beacon/advertiser from a wake stub and use way less power than light sleep. Something like the very first bt examples https://github.com/espressif/esp-idf/bl ... n/app_bt.c

So to summarize the ESP32 takes about 3mA, even with the optional 32Mhz Crystal,
while third party Bluetooth focused chips take about 10 µA. That's a huge difference!

Can we expect to see an improvement in this area with the upcoming ESP32-S3?
