27.5 Relevant Differences Between PL011 and Mini UART
● The mini UART has smaller FIFOs. Combined with the lack of flow control, this makes it more prone to losing
characters at higher baudrates. It is also generally less capable than the PL011, mainly due to its baud rate link to the
VPU clock speed.
●The particular deficiencies of the mini UART compared to the PL011 are :
·No break detection
·No framing errors detection
·No parity bit
·No receive timeout interrupt
·No DCD, DSR, DTR or RI signals
Further documentation on the mini UART can be found in the SoC peripherals document here.
 28 Control Your AWR with An Android Device
●If you want to use a mobile phone or tablet to control the robot, we first recommend that you use the
WEB application to control the robot, because the WEB application has more functions, maintenance and
updates are more frequent, and most importantly, the WEB application can be cross-platform No matter
whether you use Android system or iOS system, as long as Google Chrome is installed, you can use the WEB
application to control the robot.
●For the usage method of WEB application, please refer to 5 Using WEB Application to Control Robot.
● Our old version of the robot program is equipped with the method of using the mobile phone APP to
control, but the mobile phone APP only supports Android phones and cannot use the functions related to the
Raspberry Pi camera. The program corresponding to this function in the Raspberry Pi is appserver.py
●You can find the download address of the mobile APP in our official website. The installation method is
the same as that of the ordinary mobile phone APP.
●Open the mobile app, enter the IP address of the Raspberry Pi in the IP address field of the mobile app,
and enter 10123 in the port number. Click.Connect
