Q: Is it possible to communicate or interface with the BLE card mounted in the data logger?
A: BLE is an open protocol to read /write to the so called “CHARACTERISTIC”.
If you have a BLE device you can connect to the ML-OU-BLE to wake-up the
logger and create a transparent channel to the UI of the logger.
Scan for BLE devices filtering on devices supporting “SERVICE:”
“2456e1b9-26e2-8f83-e744-f34f01e9d701”
First, enable characteristic notification to notify the
device that data is written by the remote side. You should also write
byte ENABLE_NOTIFICATION_VALUE = {0x01, 0x00} to the channel
descriptor “00002902-0000-1000-8000-00805f9b34fb” on the BLE board,
to notify the data logger when new data is written by the BLE device,
You can read /write to the channel CHARACTERISTIC:
“2456e1b9-26e2-8f83-e744-f34f01e9d703”.
