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

Features
Model: E32-TTL-1W
E32-TTL-1W is a 30dBm wireless data transceiver module based on IC SX1278 of SEMTECH. It operates at 410 ~ 441MHz.
This module adopts LoRa spread spectrum technology, with which the module can operate in much longer distance with the same power.
It has better anti-interference performance. E32-TTL-1W is compatible with other Ebyte E32 series modules.
