E70(915T30S)-User Manual-V1.0 Website: www.cdebyte.com/enPage 2 of 11 Technical Support : support@cdebyte.com1. Introduction1.1 FeatureE70(915T30S) is wireless UART transceiver module based on the original CC1310 of TI, operating at907~922.5MHz (Default: 915MHz), TTL level and 3.3V IO port.The module has the function of data encryption & compression. The data of the module transmitted overthe features randomness. With the rigorous encryption & decryption, data interception becomes pointless.The function of data compression decreases the transmission time & probability of being interfered, whileimproving the reliability & transmission efficiency.
E70(915T30S)-User Manual-V1.0 Website: www.cdebyte.com/enPage 3 of 11 Technical Support : support@cdebyte.comNo.UsageDescription1Continuous transmissionIn this mode, the data transmitting length is unlimited:Perfectly realize continuous transmission for the highest baud rateof 115200bps.2Fixed-length transmissionAir data rate, FEC and Encryption are configurable by users;Transmitting data to the receiver in present air data rate with a mosteffective way to realize low delay and high respond.3Consumption advantageThe receiving current is 14mA, and the stand by current is 4uA.Battery-powered application is available.4WORUltra-low power consumption, suitable for the battery-poweredapplication. When the module is on the power-saving mode, thereceiving response delay time of module can adjust the powerconsumption.5Fixed transmissionModule can communicate with other modules which are work indifferent channels and addresses, it is easy for networking andrepeater.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 01refers to the address of module B, 80 refers to the channel ofmodule B), then module B receives AA BB CC (only module B).6Broadcast transmissionSet the module address as 0xFFFF, then the module cancommunicate with other modules in same channel.7FECIt has the feature of FEC (Forward Error Correction）algorithm,withhigh coding efficiency & good correction performance. In a suddeninterference, it can correct the interfered data packets proactively, sothat the reliability & transmission range are improved proactively.Without FEC, those data packets can only be dropped.8Parameter savingThe parameter will be saved after users set the parameters and itwon’t be lost if powered-off. After module powered-on again, themodule will work as previous settings.9Ultra-small size24 * 38.5mm, suitable for some application which has strictlimitation for the size.10Secondary developmentAll IO port lead out already for secondary development.11Customized ServiceIf the existing UART module cannot meet customers’requirements, Ebyte accept customization of appropriate firmware.Ebyte has provided customized wireless modules to tens ofwell-known enterprises. Please contact us for more details.12Complete seriesCC1310 has different size and packing, in which main difference isthe number of GPIO. Ebyte has completely developed CC1310,including different size, frequency, power etc.

During theprocess, the AUX keeps low level. After this process, the AUX outputs high level and starts to workas per the operation mode combined by M2, M1, M0. Therefore, the user needs to wait the AUXrising edge as the starting point of module’s normal work.3.4 AUX descriptionIt can indicate whether there are data that has been sent through wireless, or whether all wireless data havebeen sent through UART, or whether the module is still in the process of self-check initialization.No.Description1【Indication of UART output】It can be used to wake up external MCU（In continuous mode, the AUX indication isn't delayed.）
