Multifunctional Information-Delivery System For Adventure In The Wild Based On ESP32

With the advancement of society and the improvement in people's living standards,great changes have taken place in the way of people's entertainment.Wilderness adventures are gaining popularity for reasons such as relaxation,physical fitness and life.Especially for person who is under pressure for a long time,wild adventure activities can also regulate emotions and relieve stress.The areas of adventure activities are generally located in relatively remote mountainous areas,and the network conditions are worse.Today,with the continuous development of science and technology,although there are many information-delivery equipments for adventure,they are expensive and have a simple function.In the real adventure activities,such a device,which has low cost,more utility functions and simple use,is urgently needed.So a multifunctional information-delivery system for adventure is developed in this paper.For field adventures,not only can information be transmitted in an emergency,but also can the device play a variety of practical functions in the practice of exploration.This cost-effective equipment has great market demand today.Based on popular Android APP,information can be edited and transmitted to hardware device.After hardware device receives information successfully,it will be displayed automatically.An ESP32 and FreeRTOS are applied as the hardware and software platform,respectively.And a WiFi module is used to communicate with Android APP.In this way,the whole system can run without network.The communication test and performance test of the whole system are carried out at the end of this paper.The test results show that the system meets the requirements for practical application.In the communication between APP and hardware device,the communication connection and device verification are completed quickly in the background without affecting the user experience.In different situations,the system uses multiple power consumption modes to improve system usage time and meet actual usage requirements.
