Cannot see more than 3 characteristics per service on nrf51 DK

Hi community,

i experience a strange problem with the number of characteristics per service. I have implemented a custom service with 19 single byte characteristics but on my android phone and tablet only three characteristics show up (tested with nrf Master Panel). Debugging my program the service says it has got 19 registered characteristics.

I use the original J-Link firmware dated 02.21.2016 and tried the newest mbed firmware as well which results in an swd error everytime i try to flash a new program. I tried it with a very simple custom service while debugging and tracked it down that 3 characteristics is the magic number.

Is anyone experiencing the same characteristics issue or has a solution?

Best regards
