The 2 modules come completely assembled. I have opened them and carry everything. The battery, the antennas, 2 usb cables ... I was surprised by the range, as expected. Several kilometers. I do not understand that the batteries are always connected, without a switch, the device works until the battery runs out. You charge them and lasts a little while. They work right out of the box after charging the batteries a little bit. To use them seriously, use the Lora.h library from https://github.com/sandeepmistry/arduino-LoRa and the code from the following link: https://hackaday.io/project/27791-esp32-lora-oled-module. Also the examples from the Lora library.
Received the package. It comes in a carton box. Put on the antenna's. Powered on both deviced on USB power supply. One is preprogrammed to send packages. The other is preprogrammed to receive packages. When I unplugged the power on the sender, it kept sending. Ditto for receiver: on unplug it kept on receiving. I cannot yet say much about how long the batteries will last. So far it looks OK.
Sono così molto felice di possedere questi. Sono venuti esattamente come descritto e funzionano alla grande. Vorrei solo avere più soldi per tratta come questo. Mantenere il buon lavoro banggood e TTGO.
Bonjour, Contrairement au message précédent, les 6 pièces fonctionnent correctement. Par contre, les câbles USB sont bien défectueux, la prise est trop courte pour 4 d'entre eux comme indiqué sur la photo du message précédent. Merci de m'envoyer 4 câbles USB corrects.
