Hello,
I am using the nRF52 along with SDK 9.0.2. I have used both the ble_app_uart code and the twi_master_slave code to send data from a sensor over bluetooth to the nRF Toolbox UART app on Android. I can flash the code, connect to the nRF52, and read data over bluetooth just fine, but only with using an nrf_delay_ms.
If I use a delay less than about 50ms, the app disconnects from the nRF52 bluetooth, and all the LEDs light up. This is important, because I can't use too big of a delay, or my sampling rate will be too low and the quality of the data suffers.
Is it a common error for all LEDs to light up? Could the need for the delay be a hardware limitation on how quickly the nordic can send transmissions over bluetooth?
Thanks.
