有与RN4020模块一起工作的开源应用程序吗？

大家好，我想连接RN4020与我创建的Android应用程序，并使用一个具有许多特点的私人服务。我不想使用MLDP。最终目的是将RN4020与PIC连接。Android应用程序将使用SURR命令查询数据，RN4020将以特性来回答。我配置了如下模块：如果我启动旧的MLDP终端（关闭源）应用程序，它列出RN4020，但是如果我启动新的（开源），它不列出BT模块，并且如果我启动谷歌的蓝牙GATT应用程序。有人知道是否有一些与RN4020模块一起工作的开源应用程序？提前感谢

    Hi everyone, I'm trying to connect rn4020 with an android app created by me and use a private service with many characteristics. I don't want to use MLDP. The final purpose is to connect the rn4020 with a pic. The android app will ask for data with SUR command and the rn4020 will answer with the charcteristics.

I'm configured the module as follow:

SF,2 //factory reset
PZ //clear private service
SS,00000001 //Enable private service
SR,20000000 //auto advertise
PS,123456789012345678901234567890FF // create a service with this uuid
PC,12345678901234567890123456789011,12,14 // create a charcteristic with this uuid, readable and notifyable and 20 bytes long
R,1


If I launch the old MLDP terminal (close source) app it lists RN4020, but if I launch the new one (open source) it doesn't list the BT module and also If I launch the bluetooth GATT app made by Google. Do anyone know if there is some opensource app that works with rn4020 module?
Thank you in advance
