Lora Wakeup Wireless Stick v3

#1

Hi,

I followed the thread here: WiFi LoRa 32 Deep Sleep, LoRa radio leaves continuous recieve mode (assuming)

And I tried the code at the bottom and also added manual library definitions for LoRa.h and SPI.h, but it doesn’t seem to wake up as per the thread author. I also tried modifying LoRaSender and LoRaReceiver examples that do not use the heltec.h library (as this isn’t updated for the v3 devices) but they never wake up after receiving a LoRa packet either.

I compared the WiFi LoRa 32 v2 pinout with the v3 and it seems like pin26 and pin14 still are connected to the same SX pins, so I think the code should work. Has anyone gotten something like this to work with the v3 boards?

I figured it out. The pinout is as follows which means that the ext_wakeup needs to be set to 14, not 26 as per the code in the link in my first post.

/** LORA RESET */

int PIN_LORA_RESET = 12;

/** LORA DIO_1 */

int PIN_LORA_DIO_1 = 14;

/** LORA SPI BUSY */

int PIN_LORA_BUSY = 13;

/** LORA SPI CS */

int PIN_LORA_NSS = 8;

/** LORA SPI CLK */

int PIN_LORA_SCLK = 9;

/** LORA SPI MISO */

int PIN_LORA_MISO = 11;

/** LORA SPI MOSI */

int PIN_LORA_MOSI = 10;
