RN4870/71 Bluetooth Low Energy Module User’s Guide 2.6.9 &,<MAC>
Command & generates and assigns a random address to the local device. It accepts one input parameter which is a 6-byte random address. This random address can be a static or a private address. For format of random address, please refer to Bluetooth Core Specification version 4.1, Vol 3, Part C, Section 10.8. If the device is currently advertising, the advertising address immediately changes to the assigned random address.
Example:
&,DF1234567890 // Set random address to DF1234567890
Response:
AOK // Success ERR // Syntax error or invalid parameter
2.6.10 &C
Command &C clears the random address and uses local MAC address for advertise- ment. If the device is currently advertising, the advertising address immediately changes to the local MAC address.
Example:
&C // Clears random address and uses MAC address
Response:
AOK // Success
2.6.11 &R
Command &R generates a resolvable random address and assigns it as the current random address. Such resolvable random address becomes the output to UART as the response of this command. If the device is currently advertising, the advertising address immediately changes to the new resolvable random address.
Example:
&R // Automatically generate and assign a resolvable // random address
Response:
Assigned resolvable random address
2.6.12 A[,<hex16>,<hex16>]
Command A is used to start advertisement. The advertisement is undirected connectable. By default, or when command A is issued without a parameter, the advertisement is set as a fast advertisement at first (at a fast advertising interval of 20 ms), followed by a low-power slow advertisement after 30 seconds (slow advertisement interval of 961 ms). Command A is followed by two optional 16-bit hex parameters which indicate advertisement interval with unit of millisecond and total advertisement time with unit of 640 ms, respectively. After the total advertisement time has elapsed, the advertising stops along with a status string indicating the same. The optional second parameter must be larger than the first parameter in actual time. When a parameter is used in command A, the fast advertisement time-out is no longer effective and the advertise- ment with the interval parameter can last forever if there is no second input parameter, or not up to the time indicated by the second input parameter.
Default:
Fast advertisement interval for indefinite time
Example:
A,0050,005E // Start advertisement with interval of // 80 millisecond for 60 seconds
Response:
AOK // Success DS50002466C-page 32  2016-2018 Microchip Technology Inc. Document Outline Trademarks Table of Contents Preface Chapter 1.
