I recommend you enable TLS session resumption. It will take the 1-2 second TLS negotiation to ~100-150ms on repeat connections. Here's how I implemented it (this is running in IDF v4.4.1): void *serializedSession=malloc(2048); if (nvs_get_blob(main_flash_handle,"tls_session",serializedSession,&sessi...

Just bumping this -- can someone from Espressif comment on whether it should be possible to get to 130ua with the bare C3 WROOM module in light sleep?

Thanks,

Hi, I'm working to put a ESP32-C3 into light sleep and trying to achieve the datasheet rating of 130ua in that mode. Unfortunately, I've not been able to get the power consumption below 275ua. I am using a bare ESP32-C3 module (ESP32-C3-WROON-02-N4) -- I soldered the leads to it directly and am meas...

Hi, I've assembled my first prototype ESP32 PCB and cannot get my code to boot up. I have a ESP32D0WDQ5 installed and I am able to successfully flash my code with an FTDI serial cable: Connecting........__ Chip is ESP32D0WDQ5 (revision 1) Features: WiFi, BT, Dual Core, 240MHz, VRef calibration in ef...

Hi, I'm working on a device that uses the ULP to poll a sensor in the background and wakes periodically to upload data. Everything is working just as it should, but there are some power consumption anomalies I cannot seem to fix. In particular, on first power-on, the device connects to wifi, syncs w...
