I need transfer a data table which is not big, only 20 lines with 2 columns. I assigned a service for a line, with 2 charactors are for two columns. The first charactor is 4 bytes and the second charactor is 20 bytes. So there will be 20 services for the 20 lines data, with 2 charactors for each lines.

But when there are more than 5 services, the program will can't run normally. Even I modified the BLE_DB_SIZE, can't it up to 8 lines. How can I make it support to up to 20 lines?
