2 How to use?
2.1 Module working state
(1) After the module is power on, the indicator lights flash 3 times, indicating that the module is in
the broadcast state . At this time , the module is in a detectable state , and the mobile phone can
search the module . At this time , the module can connect and modify the parameter through our
APP.
(2) Press the button for three seconds, the module light flash once, and the module enters a low
power state.
Press the button again for three seconds, the indicator flashes three times, and the module wakes
back into the broadcast state.
You can modify the module parameters at this point.
Note: CC2541-Beacon can only modify the parameter for the first time, the module will
reject the connection on the second connection, and the forced connection will timeout.
Because the connection can only be connected once, the user is advised. Modify all
parameters once and then use them. Otherwise, if you can't connect the second time, you will
have to press two buttons once for three seconds, or reboot the module, which will be very
inconvenient. It is therefore recommended that all parameters be modified at one time.
