In them I put videos every week of microcontrollers, arduinos, networks, among other subjects. Relevant settings include: // 15.6kHz bandwidth, 4/8 coding rate, spreading factor 9 (512), low data rate optimization off, AGC on, // RH_RF95_REG_1D_MODEM_CONFIG1 0x1d, // RH_RF95_REG_1E_MODEM_CONFIG2 0x1e, // where the last parameter (0x04) turns the AGC on. Linked In. display.setFont(ArialMT_Plain_10); //configura a fonte para um tamanho maior It makes use of the Arduino LoRa Library by Sandeep Mistry and displays RSSI and SNR of the received data. Since there is no documentation, I simply queried all ADC pins in a hope to get one with some voltage readings. This is Heltec's model, which is at 433 MHz and works very well. Packets consisted of my Amateur Radio callsign followed by a space, a # character, and a sequential number. In order to keep the product appearance as much as possible The mini is based on the 1.02 inch e-paper screen size, and theshell is designed based on this LILYGO T-Display-S3 ESP32-S3 1.9 inch ST7789 LCD Display Development Board WIFI Bluetooth5.0 Wireless Module 170*320 Resolution, LILYGO TTGO T-Display Keyboard For LNURLPoS ESP32 WiFi And Bluetooth 1.14 Inch LCD Control Module Development Board Support TF Card, LILYGO TTGO T5 V2.3.1_2.13 Inch E-Paper Screen New Driver Chip DEPG0213BN / GDEM0213B74 /GDEM0213B74(1)(1), LILYGO Mini E-Paper Core 1.02 Inch TF Card ESP32 PICO / T- U2T USB to TTL Downloader(1)(1). good news: 868MHz (EU) / 915MHz (US) Version now avaliable on Aliexpress--.

Those complaining should realize that scientific writing in any language is usually easier than other forms to understand. Today, we have two .INO programs, the Sender and the Receiver. Lectura specs if (!LoRa.begin(BAND,PABOOST)) I also try it but can got signal only about 1m distance (I have 4 boards). I translated the manual from Portuguese and will deliver it to you in a PDF file. On the other hand, the LoRa protocol is robust enough to cope with even a large offset.
