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.
I'm so very glad to own these. They came exactly as described and work great. I only wish I had more money for treats like this. Keep up the good work banggood and 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.
