https://devzone.nordicsemi.com/f/nordic-q-a/92963/basic-program-using-nrf9160-sip-using-esp32Hello all, I was programming the nrf9160 SiP using esp32 over UART and wanted to know how do I connect ESP32 to the nrf9160 SiP and upload the code through ESP32 over to nrf9160 via AT commands. Please guide me through the same.
