Hi,
I am using CC2640 controller with ble_sdk_2_02_01_18 and tirtos_cc13xx_cc26xx_2_20_01_08. Development is done using Code Composer Studio 7.4.0. Modified sensortag example according to application. I am trying to send 40 bytes of data in two packets with 100ms delay in between from device to mobile phone for every 3sec using periodic event. In Mobile, I am using nrf_connect app to see the raw data. But there is a change in ms(instead of 3sec it's taking 3.06sec ,2.64sec,2.8sec,2.96sec) for every packet received on mobile and receiving packets at different intervals(2.4sec,2.8sec,3sec,4sec,4.8sec,3sec etc). What is the delay between sending packets from device to mobile using BLE? Is the issue is from the device side or mobile app side?
