1. Introduction

1.1 Feature

E70(915T30S) is wireless UART transceiver module based on the original CC1310 of TI, operating at

907~922.5MHz (Default: 915MHz), TTL level and 3.3V IO port.

The module has the function of data encryption & compression. The data of the module transmitted over

the features randomness. With the rigorous encryption & decryption, data interception becomes pointless.

The function of data compression decreases the transmission time & probability of being interfered, while

improving the reliability & transmission efficiency.

No. Usage Description
In this mode, the data transmitting length is unlimited:
1 Continuous transmission Perfectly realize continuous transmission for the highest baud rate
of 115200bps.
Air data rate, FEC and Encryption are configurable by users;
2 Fixed-length transmission Transmitting data to the receiver in present air data rate with a most
effective way to realize low delay and high respond.
The receiving current is 14mA, and the stand by current is 4uA.
3 Consumption advantage
Battery-powered application is available.
Ultra-low power consumption, suitable for the battery-powered
application. When the module is on the power-saving mode, the
4 WOR
receiving response delay time of module can adjust the power
consumption.
Module can communicate with other modules which are work in
different channels and addresses, it is easy for networking and
repeater.
5 Fixed transmission For example: module A transmits AA BB CC to module B (address:
0x00 01, channel: 0x80), HEX format is 00 01 80 AA BB CC (00 01
refers to the address of module B, 80 refers to the channel of
module B), then module B receives AA BB CC (only module B).
Set the module address as 0xFFFF, then the module can
6 Broadcast transmission
communicate with other modules in same channel.
It has the feature of FEC (Forward Error Correction）algorithm,with
high coding efficiency & good correction performance. In a sudden
7 FEC interference, it can correct the interfered data packets proactively, so
that the reliability & transmission range are improved proactively.
Without FEC, those data packets can only be dropped.
The parameter will be saved after users set the parameters and it
8 Parameter saving won’t be lost if powered-off. After module powered-on again, the
module will work as previous settings.
24 * 38.5mm, suitable for some application which has strict
9 Ultra-small size
limitation for the size.
10 Secondary development All IO port lead out already for secondary development.
If the existing UART module cannot meet customers’
requirements, Ebyte accept customization of appropriate firmware.
11 Customized Service
Ebyte has provided customized wireless modules to tens of
well-known enterprises. Please contact us for more details.
CC1310 has different size and packing, in which main difference is
12 Complete series the number of GPIO. Ebyte has completely developed CC1310,
including different size, frequency, power etc.

2. UART functional description (default)
2.1 Fixed transmission
Hex Description
The format: :Hexadecimal, such as：00 03 04 AA BB CC
00 03 is the address of receiving module；04 is the channel ；AA BB CC is the transmission data。
Transmitting module A Hexadecimal Address：00 01；Channel :02

Receiving module B Hexadecimal Address：00 03；Channel :04

Receiving module C Hexadecimal Address：00 05；Channel :04
Receiving module D Hexadecimal Address：00 07；Channel :06
Module A must be in fixed mode.
Module A Transmitting data Hexadecimal 00 03 04 AA BB CC
Module B receiving data Hexadecimal AA BB CC
Module C receiving data Hexadecimal No
Module D receiving data Hexadecimal No
Only the modules with matched address and channel can receive the data.
In fixed transmission, modules only support 1 packet length (pls refer to electrical parameters). If the data
packets exceed, then it needs to be subcontracted automatically.

Receiving module B Hexadecimal Address：00 03；Channel :04
Receiving module C Hexadecimal Address：00 05；Channel :04
Receiving module D Hexadecimal Address：00 07；Channel :06

Module C receiving data Hexadecimal AA BB CC
Module D receiving data Hexadecimal No
All the module with this channel can receive the data.
In fixed transmission, modules only support 1 packet length (pls refer to electrical parameters). If the data
packets exceed, then it need to be subcontracted automatically.

2.3 Broadcast address
1. For example, set the address of module A as 0xFF FF, and the channel as 0x04.
2. When module A works as the transmitter (transparent transmission), all the receiving module with the
channel 0x04 can receive the data, so as to realize the broadcast.

2.4 Monitoring address
1. For example, set the address of module A as 0xFF FF, and the channel as 0x04.
