ESP32 Forum

Hello,

Maybe can be some stupid question, but everybody talks about IoT, long battery life and higher coverage.
I have some question about:
- long range LPWAN for IoT applications (more than 1km range similar to LoRa or Sigfox) ?
- hidden SSID for the Wi-Fi network ?

Regards, Xatax

Re: hidden ssid for WiFi.

When the ESP32 offers itself up as a WiFi access point using the api "esp_wifi_set_config" its parameter is an instance of a "wifi_config_t". This has a flag called "ssid_hidden" and if set to true, the ESP32 will not broadcast its SSID.

Hi xatax79,

Lua RTOS is available on github for ESP32:

https://github.com/whitecatboard/Lua-RTOS-ESP32

Lua RTOS has support for LoRa WAN. All is programmed in Lua in an easy way, for example for send a LoRa frame you only need to write this:

lora.setup(lora.BAND868)
lora.setAppEui("70XXX57ED0000XX0")
lora.setAppKey("8CXXXX5A80XXXX0FXX18XXBCXX41XXXX")
lora.setDevEui("XXB3XX7E000XX000")
lora.setDr(5)
lora.setAdr(false)
lora.join()
lora.tx(false, 1, pack.pack(25.2))

Best regards,

Lua RTOS team
