Hi, the code below should work to send the time to the device: it opens the connection, sends the command to update date, and then closes the connection.
import asyncio
from time import time
from bleak import BleakClient
UUID_NORDIC_TX = "6e400002-b5a3-f393-e0a9-e50e24dcca9e"
UUID_NORDIC_RX = "6e400003-b5a3-f393-e0a9-e50e24dcca9e"
async def main(address):
buffer_size = 20
print(f"Connecting to {address}...")
async def send_command(command):
c = command
while len(c) > 0:
await client.write_gatt_char(UUID_NORDIC_TX, bytearray(c[0:buffer_size]), True)
c = c[buffer_size:]
async with BleakClient(address) as client:
print("Connected")
print(f"Time: {time()}")
await send_command(bytes(f"setTime({time()});\n", "utf-8"))
asyncio.run(main("d8:ee:7c:31:a9:c0"))
I'm using something similar to this to periodically sync weather data and my personal agenda with the device
