Limit of 6 GATT Server Characteristics in Connectivity Software 3.0.1

+2 votes

I am unable to add more than 6 GATT Characteristics. I have tried in my firmware over UART and via S-Center. It always errors on the 7th characteristic. 

Is there a way to increase the characteristic limit? Also is there any access to the connectivity software source?

"3.0.1.1"                                                                                    
OK

Support answered this for me. It a limitation of memory allocation. By the 6th characteristic there is no more memory that can be allocated for new characteristics. I believe its unspecified because it depends on what other allocations have already be made.

If the documentation doesn't tell you how to do it, then it's most likely you can't do it.

If you can't find the source code for the connectivity software with a simple search, then it's most likely not available.
