Newbie Questions Related to RAK11160

Hi All,
About to use RAK11160 for the first time and had few very basic questions.

1- While posting this, I wasn’t able to find category for RAK11160. I went ahead and slelected WisBlock. Not sure if we have one.
2- RAK11160 can talk with LoRa P2P with RAK3172 module?. RAK3172 behaving as remote sensor node and RAK11160 as gateway to cloud.
3- In order to communicate with Arduino and program this module (both LoRa and WIFI code), we only need ST_UART2 pins? (TX and RX) as shown in sample schematic. We only program ESP module, ESP internally handles communication with LoRa module. In that case shouldn’t we be connecting with ESP UART Pins instead?

4- Above schematic does not show boot pin wiring. Is it required?

Welcome back to forum @omerattiqahmed ,

  1. RAK11160 is a WisDuo module but if you need in WisBlock Core formfactor, you can find it here - STM32WLE5 for LoRaWAN® + Espressif ESP32-C2 BLE and WiFi | RAK11162
  2. Yes. That is possible. That’s one of the usecase for RAK11160.
  3. Yes. You only need ST_UART2. The ESP are not programmed internally. The STM32WL communicates to it via ESP32 AT Command. ST_UART1 is use for this ESP32 AT Communication.
  4. Boot pin is not required. But if you plan to upload an hex file to STM32WL of RAK11160, you will need it. For Arduino IDE uploading, it not need needed.
