Android Question bluetooth, Service and Characteristic problem

CorryWestSide · May 13, 2024

The company told me this word:
A Characteristic is used to write the system and you have to send the START there

START (0x05,0x06,0x40,0x00,0x08,0x01,0x5B,0x95)

WRITE, WRITE_NO_RESPONS
UUID 00005302-0000-0041-4c50-574953450000

-----------------------------------------------------------
the other is used to write to the system and receive the answer:

NOTIFY
UUID 00005303-0000-0041-4c50-574953450000

pls help, i dont know how to implement this

Before writing an app to control the device, have you done it using nRF Connect?

Eg by writing the specified 8 bytes to characteristic 00005302-0000-0041-4c50-574953450000

yes of course, i first do a lot of try with nRF connect but without any resoult, i just set true the 00005303-0000-0041-4c50-574953450000 characteristic and then i send the data in characteristic 00005302-0000-0041-4c50-574953450000 but i dont receive nothing

i actually have to receive a "string" that will are row by row of an EVA-DTS file and only then i can take them and re-group in a file but i dont receive nothing
