Hi , I would like to know about Bluetooth 5 compatibility with smart phones having Bluetooth 4.x The observation is-
a)the android application scanning for BLE device finds the device with Bluetooth 4.2 faster where as app is taking long time to find Bluetooth 5 device visibility.
b)Bluetooth 5- We have the default advertising interval of 40ms- then we are suppose to get atleast 10+ callbacks in a sec(as it broadcasts 25 adv packets per second). But android is not getting even a single callback for seconds but works fine for some seconds where as same works fine with Bluetooth 4.x.
Seems like this is due to Version incompatibility (android devices with Bletooth 4.x and hardware Nordic Bluetooth 5)
There is a solution mentioned Have a look on the question asked in Nordic devzone-- https://devzone.nordicsemi.com/questi...
Let me know how to use 1Mbps on Bluetooth 5 to have GAP and Gatt working as it does in Bluetooth 4.x or some other way to have back compatibility and also about is this changes supports longer range. If you want any clarification please get back.
Thanks in advance Pavan
