HƯỚNG DẪN SỬ DỤNG VÀ CẤU HÌNH
Chân M0,M1 nối GND để truyền nhận bình thường hoặt nối với GPIO của vi điều khiển để thay đổi các Mode như dưới đây
Mode(03) |
M1 |
M0 |
Mode introduction |
Remark |
Mode 0 Normal |
0 |
0 |
Serial port open, wireless channel open, transparent transmission. |
The receiver must be in mode 0 or mode 1 |
Mode 1 Wake-up |
0 |
1 |
Serial port open, wireless open. The difference between normal mode and wake-up mode is it will increase wake-up code automatically before data packet transmission so that it can awaken the receiver working under mode 2 |
The receiver could be in mode 0, mode 1 or mode 2. |
Mode 2 Power saving |
1 |
0 |
Serial port closed, wireless is under the air wake-up mode. It will open the serial port and transmit data after receiving the wireless data. |
1, the transmitter should be in mode 1 2, cannot transmit under this mode |
Mode 3 Sleep |
1 |
1 |
The mode will sleep and can receive parameter setting command. |
For details, pls refer the operating parameter elaboration |

Package Included
1 x Wireless Transceiver Module
Mạch thu phát RF UART Lora E32-TTL-100, 433Mhz sử dụng chip SX1278 của SEMTECH
Feature:
E32-TTL-100 is a wireless transceiver module based on SX1278 from SEMTECH(can be transmitter and receiver both). It adopts LoRa spread spectrum technology, with this technology the transmitting distance and penetration ability of the module improved more than 1 times compared with traditional FSK.The module features FEC (forward error correction) algorithm, which ensure it's good anti-interference ability. E32-TTL-100 can be compatible with other E32 modules.
