YUNOFDM 2.4G module manual

1.General Description

YUNOFDM is a point-to-point broadband access and data transmission module. The

product is based on a custom wireless communication protocol and uses OFDM

(Orthogonal Frequency Division Multiplexing). YUNOFDM modules has two ipex

connectors for connecting 3dBi antenna, supports 1T2R MISO mode, the system

configures one of them transmitting depending on better received signal quality at two

antennas by system automatically recognizes. YUNOFDM only supports 10 MHZ

bandwidth. flattening System architecture design, effectively reduce System latency,

improve the ability to transfer and have the transmission distance data throughput big

strong anti-interference characteristics of the product is the first of SOC (System on Chip)

chips, provides the high level of integration point-to-point transmission module, greatly

reduce the power consumption of the System, and reduce the module size, satisfy the

customer the demand of the development of UAV video monitoring, YUNOFDM module

supports 2.4g frequency band.

2.Application

YUNOFDM module provides upper computer four interfaces USB, RJ45, UART0 and

COMUART for connection. Two modules on the platform can realize the connection of air

port and realize wireless data transmission. The details are shown in the figure below:

With flow control serial port UART0, 1.8v voltage domain, default baud rate 115200bps, the highest theoretical value can support 19.5mbps. COMUART is used for flight control, directly controlled by CP, with lower delay. 3.1.4.2 GPIOs Six GPIOs are reserved in the module, which can realize the functions of handshake, interaction and interrupt indicator. 3.

4.2 STARTING The main module/slave module boot process is initiated by AT+CFUN=1. After YUNOFDM module power on, the internal will automatically carry out the network/search, synchronization, chain building process, and internal opening Status is actively reported. The upper computer can judge the status of the module according to the result of active report.

identity matching. 3. Boot access is completed only after authentication is bidirectional. 4. The AT instruction used to set the device ID is: AT^DTTEST=< CMD >(AT+CFUN=0/ set in production test scenario). 5. The AT instruction used to set the device ID is AT^DPDIL=< ID >. 6. After setting, you need to power up and start up again, which can take effect permanently. 7. The AT instruction used to query the device ID is AT^DAOCNDI? 4.4 Frequency YUNOFDM only supports 2.4G band. FCC statement 15.19 1.

for all other operating configurations, including portable configuration with respect to Part 2.1093 and different antenna configurations. A module or modules can only be used without additional authorizations if they have been tested and granted under the same intended end‐use operational conditions, including simultaneous transmission operations. When they have not been tested and granted in this manner, additional testing and/or FCC application filing may be required.
