Hello guys! I am testing the NRF52-DK along with the dongle for a IMU tracker device.
I am new to zephyr, nordic and BLE and having some troubles understanding zephyr and BLE and wanted to ask for a few pointers.
If this does not belong here then feel free to remove this post
What I'm trying to do is the following:
NRF52-DK:
Obtain samples from IMU (16bit 6axis) and fill a 1200 byte buffer (100 IMU frames)
Transfer the 1200 bytes (raw data) to the dongle via BLE in multiple blocks/transfers.
DONGLE:
Print/log the data received by the dongle to a terminal/file.
PC:
Use the data from the log file or terminal to reconstruct the IMU data and do something with it.
Questions:
1. What is the industry standard block size for this kind of transfer?
2. Can I somehow remove the prefix from the dongle output so that only the raw data is being logged? ("Attribute value written, handle: 0x12, value (0x):")
3. Is there a simple example for this kind of transfer using NCS zephyr? I have looked into the "throughput", "peripheral_uart" and "shell_bt_nus" examples but I find them being very comprehensive and hard to follow with multiple function calls within each other.
I was expecting to find a simpler example (fewer lines of code) which would be easier to dig through at this point.
NOTES:
-I have already covered the IMU reading and buffer filling at this point.
-I'm not worried about speed of transfer at this point.
