Frequently Asked Questions
Question:Does the E72 burning program use a serial port or JATG download?
Answer:The tool we use is the XDS100V3.0 JTAG interface.
Question:Is the module severely overheated during use and unable to be used?
Answer:Please confirm how many volts are supplied? Is the antenna compatible? If there are no issues with the above, please contact customer service.
★ Question: 1. Does it support one master and multiple followers; 2. Is there a requirement for the length of data to be transmitted to the module through the serial port? If not, is there a requirement for the transmission interval of each data packet? When the Bluetooth module is in transparent mode and the baud rate is 19200, data is sent to the Bluetooth module through the serial port for communication between the two Bluetooth modules. Under what circumstances will packet loss occur?
Answer:BT02 does not support one master and multiple slaves, while E74 can send data from BT02 slave to host. Serial port baud rates of 19200 and below can support continuous transmission, allowing users to send data of any packet length at any time. The host sends to the slave, preferably no more than 20 bytes at a time.
★ Question: When the Bluetooth module is used as the host for scanning, can it read the broadcast data of other devices scanned through the serial port?
Answer:There is no such function.
★ Question: E104-BT021 and BT02 are used as slave devices, and broadcasting is enabled. The mobile phone Bluetooth actively connects, but after a period of time, it still cannot be connected. 2. As the host, it returns and there is no apparent problem. FCF2E6ED7D7C is a 6-byte mobile phone Bluetooth MAC.
Answer:1. Please pay attention to the instructions of the bond command. The MAC address is sent in hexadecimal format; 2. The problem of not being able to connect, please ensure that the Bluetooth on your phone is working properly. You can try turning off the Bluetooth switch on your phone and then turning it back on.
★ Question: The manual states that master-slave character matching can be achieved one-to-one. May I ask if it is possible to do one to many or many to one?
Answer:No, it can only be one-on-one.
★ Question: Is there any additional configuration required to connect the module to the computer, or can it be directly connected?
Answer:As long as the computer supports 4.0 and requires software support, it can be connected.
★ Question: A 3V battery must still work at 70%, which means it can still work at 2.1V. After testing, I found that it cannot work at 2.3V. Is there a solution to this?
Answer:The manual states that it must be greater than 2.35V to function properly.
★ Question: Does this module support the Apple system? What testing software should Apple phones download?
Answer:Support, both "LightBlue" and "BLE Assistant" are available.
★ Question: What is the lowest power consumption?
Answer:1.6uA
★ Question: How many kilometers is the line of sight test?
Answer:The actual visible distance is 80 meters
★ Question: If the computer itself has Bluetooth, you need to purchase a Bluetooth chip to install it on the hardware device, and then intercept the Bluetooth chip through the Bluetooth of the computer and phone. Can this function be achieved using E74?
Answer:The E74 series products are transmitted and received through serial ports, and our E74 product can solve the above problems
★ Question: Does E74-2G4M02S support pairing with mobile phones?
Answer:support! Please use an Android phone (system version 4.3 or above), an Apple iPhone 4s or above, or an iPad with BLE function, all of which can establish Bluetooth connection with the module without password pairing process.
