Hello All,
I am working on the NRF52810 with sdk 15.3 softdevice 6.1.1
I have added the 3 service like TX power, Battery Service, Immediate alert in my program.
I wanted to add eddystone service to the same program. But i am not getting any example that can be used for the adding eddystone sevice to exisiting services.
Find the (main.c file) code attached, please check.
Please provide your input.
Regards ,
Rohit
