Hi everybody
I'm working on an application where I want to sample microphone data with the adc (NRF52 DK board, nRF52832) and send it over BLE to a central device. I've already read quite a lot about creating your own BLE service and characteristics but I'm wondering if there is a good starting example or already existing code for my application.
Here are some application requirements:
around 100kb/s data stream
data arrays, probably as large as possible (max. MTU size)
sampled with 4kHz/8kHz/16kHz, 10 bit ADC
Low power application
example commands from central node to peripheral node: start streaming, stop streaming, etc.
The only real example I found so far is BLE NUS service from the ble_app_uart example (using ble_nus_string_send). Is this the way to go for transmitting large amounts of data? (also regarding power consumption)
Best and thanks for your time
Nick
