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.

Description
In this mode, the data transmitting length is unlimited:
Continuous transmission
Perfectly realize continuous transmission for the highest baud rate
of 115200bps.
Air data rate, FEC and Encryption are configurable by users;
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.
Consumption advantage
The receiving current is 14mA, and the stand by current is 4uA.
Battery-powered application is available.
Ultra-low power consumption, suitable for the battery-powered
WOR
application. When the module is on the power-saving mode, the
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.
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).
Broadcast transmission
Set the module address as 0xFFFF, then the module can
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
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
Parameter saving
won’t be lost if powered-off. After module powered-on again, the
module will work as previous settings.

Description (STM8L MCU)
The UART module is TTL level., please connect to the MCU of TTL level.
For some MCU works at 5V DC, it may need to add 4 ~ 10K pull-up resistor for the TXD & AUX
pins.
3.3 Reset
No.
Description
When the module is powered on, AUX outputs low level immediately, conducting hardware
self-check and setting the operating mode on the basis of the user parameters. During the
process, the AUX keeps low level. After this process, the AUX outputs high level and starts to work
as per the operation mode combined by M2, M1, M0. Therefore, the user needs to wait the AUX
rising edge as the starting point of module’s normal work.
3.4 AUX description
It can indicate whether there are data that has been sent through wireless, or whether all wireless data have
been sent through UART, or whether the module is still in the process of self-check initialization.
No.
Description
【Indication of UART output】
It can be used to wake up external MCU（In continuous mode, the AUX indication isn't delayed.）

【Indication of wireless transmitting】
1. Under subpackage transmission mode, the internal buffer size depends on the subpackage
size, if the data packet length is 1024 bytes, the corresponding buffer is 1024 bytes, when the
AUX=1, user could transmit data continuously ，no more than 1024 bytes .
2. Under continuous transmission mode, AUX=1, there is no limitation on user data input
length.
3. Under WOR transmission mode, AUX=1, user could continuously input less than 84 bytes.
4. AUX=1 means the serial port data has been transmitted completely.
【Configuration procedure of module】only when resetting and exiting sleep mode
4. Choose antenna
