Re: plain no-radio microcontroller for a low power sensor node

Thank you for the clarification in deep sleep, solved. In arduino-esp32 framework, To change cpu clock frequency in setup() function (for example, due to reset reason poweron/wakeup) Included header, Is the following way available for example 10MHz? setCpuFrequencyMhz(10); // ESP32-WROOM-32D module ...

plain no-radio microcontroller for a low power sensor node

Hi, To implement a battery powered sensor node, I want to use ESP32 as a PLAIN(no-radio) microcontroller. This is a LoRaWAN Class A sensor node, Combining ESP32-WROOM-32D module (as a host) connected to RHF76-052DM Ai-Thinker LoRaWAN module. The only time using WiFi/BLE wireless feature is while con...
