Precautionsforuse 2.1BLEdescription 2.1.1MTU Referstothe payload size ofBLE airsingle packet data.The MTU ofthe BLE4.0/4.1 protocol is27 bytes, which can be expanded to 251 bytes from the MTU of BLE4.2 and higher. In actual use, the single packet data is MTU-3, that is, the user can send a maximum of 24 bytes using BLE4.0/4.1 protocolsinglepacket,andBLE4.2andhigherversionscanbeexpandedto247bytes. Itshouldbenotedthatinactualapplications,theMTUofdifferentdeviceswillbedifferent. 2.2Precautionsformoduleapplication 2.2.1Judgmentconditionsfortheroleofmasterandslave When the module actively scans and connects to other Bluetooth devices, the module assumes the role of the master in this connection; when the module is connected by other Bluetooth devices due tobroadcastingitself,themoduleactsastheslaveinthisconnection. 2.2.2Responseofdistancetodatatransmissionrate The module uses PCB antenna. Compared with ceramic antennas, BLE wireless signals have stronger transmitting and receiving capabilities with external antennas. Nevertheless, the data transmissionspeedofthemodulewillstillbeattenuatedduetotheincreaseindistance. 2.2.3Moduledatatransmissionspeedchanges The data transmission speed of the module will decrease as the distance increases.And because the module sends data in the form of pollingconnections,when there are multiple connections, the total data sending time will vary due to the distance and the number of connections. In the case of multipleconnections,itisrecommendedtoaddacertaindelaybetweeneachpacketofdata. 2.2.4Modulecurrentmaybetoohighinlowpowerconsumptionmode When the module is connected, the connection will remain undisconnected in low power consumption mode, so the current of the module may be slightly higher, but it is always less than 100uA.

Rev 1.1 - 9 - sales@nicerf.com 7.FunctionDescription 7.1Roledescription The module supports three roles: master, slave, and master-slave coexist. These three types can be modifiedbysendingATcommandAT+CONS. The module supports up to 20 connections, supports transparent transmission, and supports manual andautomaticconnections. 7.1.1Host Command AT+CONS=x,y. When the value of y is greater than 0, the host role is enabled andthescanningfunctioncanbeused. In configuration mode, send command AT+SCAN to start scanning, which is used to manuallyconnecttotheslave; In the transparent transmission mode, the module will automatically scan the connected slaves. Supports one-master and multiple-slave connections.The maximum number of connections dependsontheAT+CONScommand,andthemaximumnumberisnotmorethan20. Whenthenumberofconnectedslavesreachestheset maximumvalue,themodulewillstop scanningandallscanningfunctionswillbeinvaliduntilanyslaveisdisconnected. 7.1.1.1Hostconnectionstrategy ThemodulefiltersbroadcastpacketsbyserviceUUID. UUID filtering is based on the content filtering configured byAT+UUID, and this condition cannot beclosed. The module will analyze the scanned broadcast packet during scanning. If the broadcast packet contains Service UUID and the UUID is the same as the Service UUID of the module itself, the module will automatically initiate a connection. After the connection is established, the module as the host role will try to read the Characteristic UUID under the Service UUID of the peer device. If themoduledoesnotreadtheServiceUUIDandtheCharacteristicUUIDunderit,ortheUUIDvalue readdoesnotmatchthemoduleitself,themodulewillautomaticallydisconnectitsconnection. Thisfilterconditionappliestomanualconnectionandautomaticconnection.
www.nicerf.com BLE5101 NiceRF Wireless Technology Co., Ltd. Rev 1.1 - 10 - sales@nicerf.com 7.1.2Slave CommandAT+CONS=x,y. When the value of x is greater than 0, the slave role is enabled andthebroadcastfunctioncanbeused. SendcommandAT+MODE=Ainconfigurationmodetostartbroadcasting. Inthetransparenttransmissionmode,themodulewillautomaticallybroadcastitself. Support one-slave multi-master connection. The maximum number of connections depends ontheAT+CONScommand,andthemaximumnumberisnotmorethan20. The broadcast content includes the device name, mac address, and Service UUID required fortransparentdatatransmission. When the number of connected hosts reaches the set maximum value, the module will stop broadcasting itself, and all broadcasting functions will be invalid until any host connection is disconnected. 7.2Powermode Themodulesupports2powermodes:lowpowerconsumptionmodeandwake-upmode. 7.2.1Lowpowermode Lowpowerconsumptionmodemeansthat whenthemoduleentersthismode,theBLE functionwill continue to run, turn off some peripherals, stop broadcasting and scanning, in order to minimize the powerconsumptionofthemodulewhenitisrunning. Howtoenterthelow-powermode:pulluptheCSpin,whentheindicatorpinispulledlow,itmeans thatithasenteredthelow-powermode. Howtoexitthelow-powermode:pulldowntheCSpin. In low-power mode, when there is an undisconnected connection, such as the module receives data from the opposite end, or when the connection status changes, the module will temporarily wake up and process related tasks.After thetask iscompleted, the module will enter immediatelywhen there isnotasktemporarily.Sleep. 7.2.2Wakemode Wake-up mode refers to the state when the module is operating normally outside of the low-power mode,andallperipheralsandfunctionsareoperatingnormally. Howtowakeup:pulldowntheCSpin.

All data is transmitted in ASCII format. The module sends the data to every connected Bluetooth device through polling connection when the data is transparently transmitted. Under extreme conditions,itcannotbeguaranteedthateverydevicewillreceivethedata. Donotonlysendthedata"+++\\r\\n" within50msduringdatatransparent transmission,otherwise the modulewillentertheconfigurationmodeduetomisoperation. 7.4UUIDdescription TheUUIDvalueslistedinthetablecanbemodifiedbyATcommands,exceptforUUIDattributes. 7.5Connectionhandle 1. Normally, the connection handle of the module is the number of the specified link (0-19). In principle,thehandleofthemoduleconnectionmaynotbethesameeachtime. 2. In the case of a multi-master and multi-slave connection, each module on the connection handle mayhaveamasterroleoraslaverole,dependingontheconnection. 3.ThedesignatedlinkcanbeoperatedthroughATcommands. 7.6Airupgrade（OTADFU） The module supports over-the-air upgrade of firmware, and the best functional experience can be obtainedthroughover-the-airupgrade.Userscanalsocustomizethefirmwaretheyneed.

The"\\r\\n"appearingintheATcommandsetareallcarriagereturnandlinefeedcharacters. Command sending format:All commands begin with "AT" and end with "\\r\\n". Commands mustbecapitalizedexceptforparameters. Command return format: return the relevant string corresponding to the sent command, all endingwith"\\r\\n". ThesendingintervalofeachATcommandshouldbemorethan50ms. Entering the configuration modewill temporarily disable the low power consumptionmode (CSpinfunctionisinvalid). In the configuration mode, in order to prevent data interference, the data sent from other deviceswillnotbedisplayed. Whenever the command response is successful (that is, when the command success response returns OK), the program will start a 500mstimer,and after the time isup, theAT command data that can be saved at power-off will be automatically saved in the internal Flash,sowhenyousetthecommandTrytoavoidsuddenpowerfailure. 8.2Howtoenterandexitconfigurationmode 1）Howtoenter： 1. In the transparent transmission mode, "+++\\r\\n" is sent separately within 50ms. In the configuration mode entered in this way, the serial port parameter configuration is the same as the transparenttransmissionmode. 2. The transparent transmission mode pulls down the SET pin.
