Recently, the author is studying how to optimize the function of personnel positioning badges to enhance the user's sense of experience. Recently, my development team is also undergoing in-house training. I would like to take this opportunity to share the main content of the training with you, hoping to help people who are also engaged in development-related work.

In addition to the real-time positioning function, the personnel positioning badge can also set up an electronic fence for the activity range of the badge user through the cloud background, and when the user exceeds the safe range, the cloud background will automatically alarm, helping users improve monitoring efficiency. For the elderly, children, outdoor workers, etc. who are not convenient to use intelligent communication equipment, the badge can realize the function of family call and one-key alarm. When the user encounters a dangerous situation, only need to press the button of the smart badge to automatically connect with the manager in the background of the cloud to help the badge user quickly get in touch and avoid dangerous accidents.
Voice call of the M2M module in the personnel positioning badge
The realization of the call function in the personnel positioning badge mainly relies on the Voice call of the M2M module, Voice call refers to the use of communication modules to dial, answer, report phone information, hang up the phone, multi-party call, call forwarding, volume adjustment, ringing and other functions. Its application scenarios are mainly: VOIP customers, in-vehicle customers, some POS customers, wireless fixed-line, PAD consumer electronics and other places where voice calls are needed.
According to the above functional requirements, the module provides the following commands to implement these functions:
ATD Dial Call ATA Answer Phone ATH Hang Up Phone AT+QAUDCH Select Audio Channel AT+CLVL Adjust Call Volume AT+CALM Mute Incoming Call Ringtone AT+CRSL Adjust Incoming Call Ringtone Size AT+CLCC Get Call Status AT+CHLD Multiparty Call AT+CFCC Call Forwarding Function AT+CCWA Implements Call Waiting Function
Through the introduction of the above content, I hope that people who are also engaged in the development of related equipment can gain something from it. At the same time, the author believes that with the continuous upgrading of related technologies in the future, the scope of application of personnel positioning badges will gradually deepen, helping more people to achieve efficient and safe monitoring and management.
