[esp-sx1] New are the latest ‘china’ 868-915 Mhz LoRa modules This is the topic to discuss the different types ect… https://www.ebay.com/itm/SX1276-868MHz-915MHz-LoRa-Module-ESP32-OLED-Wifi-Bluetooth-IOT-Development-Board-/272895587941

You can use them for Lora (not lorawan) projects, or for anything not even related to lora at all - after all an ESP32 with an oled and battery management can have many uses in its own right. I was in the same situation as you - but only for one 433 Mhz unit - and just decided to send it away to an…

If you have 433 Mhz unit, I can buy from you.

Hi, Same problem. Directly powered with 3.3v through pins, it drains 10.2mA in deep_sleep, LoRa.sleep and displayoff. I’m waiting to receive LoRa1276 modules to test them with esp32 devboard and discover what drains the power!

I’ve received mine: https://www.aliexpress.com/item/-/32840258107.html They came nicely packaged on a plastic box that protects the OLED. The nice/weird WIFI antenna. Under it there is nothing. No components no screws. But I yet didn’t test WIFI and/or BLE. It came with pin headers, SMA pig…

Hi, Just beginning with using the things network. But how do I start with the heltec lora esp32 dev board? I just want to use an example, but I get an error. "\Arduino\libraries\TheThingsNetwork\src/TheThingsNetwork.h:9:26: fatal error: avr/pgmspace.h: No such file or directory"

I have the Heltec esp32 LoRa 868MHz dev board. #include <TheThingsNetwork.h> #include <TheThingsMessage.h> // Set your AppEUI and AppKey const char *appEui = "XXXXXXXXXXXXXXX"; const char *appKey = "XXXXXXXXXXXXXXXXXXXXXXXX"; #define loraSerial Serial1 #define debugSerial Serial // Replace REPLA…

Are you sure you selected the right board in the menu ? That error mentioning “avr” sounds like you are still trying to build for an arduino - or any other boards using AVR µControllers.

I have selected the Heltec_WiFi_lora _32 board

Hi - not sure what is happening in your code. The TTN-OTAA and TTN-ABP examples work with the MicroChip RN2483 module that has a serial connection. I suggest you try the LMiC code. Below is a working example… #include <lmic.h> #include <hal/hal.h> #include <SPI.h> #include <U8x8lib.h> #define BUIL…
