Sigfox and Lora functionality..
Since the modules are using esp3 chips, is the lora and sigfox functionality part of the esp32 chips or is it the functionality built by pycom? Trying to understand if this protocol is built into the chip (like BLE) or something pycom specifically developed?
Is this open sourced, i want to learn how this all works so i can optmise where possible.
No, in ESP32 there is only built in Wifi and BT. For lora there is another chip SX1272.
In lopy4 there is new one SX1276 which support both lora and sigfox.
