Frequently Asked Questions
★Question:How to determine if the data has been sent without the AUX pin on the radio?
Answer:Unable to determine, except for looking at the TX light.
★ Question: Can the launch start time be set through the existing software? The measured delay from the serial port to the air port is about 100ms, sometimes even higher.
Answer:The existing software cannot be set, and the delay is related to airspeed, data volume, etc.
★Question:Can both network ID and spreading factor be set?
Answer:The spreading factor is automatically set based on the selected airspeed; The address can be set, but the spreading factor cannot be set.
★ Question:The 232 interface connected to the computer and the 485 interface connected to the device are unable to communicate data.
Answer:First, use a computer to directly communicate and test if the module is communicating properly. Please check if the set parameters are correct.
★Question:Is there any time limit or requirement for the radio station to continuously send data under normal working conditions?
Answer:A buffer of 512 bytes, not exceeding the buffer size, with a 2-day aging test time.
★Question:E90-DTU, please help me check: How E90 works?
Answer:The usage method of E90 is the same as that of other radio stations, except that the length of the sub package has increased; Mesh networking is not supported, and networking can only be done in a polling point-to-point manner.
★Question:The communication between the tested DTU and PLC failed. How should I handle it?
Answer:1. Confirm that our module is communicating normally; 2. Confirm the correct RS485 wiring and confirm the PLC; 3. Set the parameters to be consistent with our module parameters.
