Dear  CYPRESS:

       when we use the  CYBLE-212020-01 module, we use this below to test the firmware, we find some issue ;

1、we choose  P0.6, P0.7 /XRES  GND VDD for download firmware , it's ok ;

2、we choose P1.4, P1.5 GND VDD of  CYBLE-212020-01 to connect  p12.6,P12.7(RX, TX) , but it's can't return date in COM tool,  how can we use it? tks;

Hi David,

Whether the  CYBLE-212020-01 send data? Do you use the Oscilloscope to check the Data flow?

HI  LingLing:

        采用PSOC6 BLE DEMO的kitprog2 的P12.6,12.7 与模块的P1.5,  P1.6 想连接, 如下图所示,

1、P12.6, P12.7 接在一起进行串口回环测试,能正常收发数据?

2、P12.6, P12.7 接P1.5,P1.4 串口无数据,示波器看不到有数据,串口无数据?这种接法是否正确??

3、如下2中固件有什么区别,分别烧录都没有数据?? 上电后,如何正常是否是以文本模式输出如下:

              @E,003B,BOOT,E=0101011A,S=030300FA,P=0103,H=05,C=01,A=00A050421A63
