I am trying to communicate with a BT832X module ( https://ro.mouser.com/datasheet/2/915/BlueNor_BT832X_datasheets-1518727.pdf ) using a PIC microcontroller ( http://ww1.microchip.com/downloads/en/DeviceDoc/39755B.pdf ), through I2C bus interface.
Problem is that I am not sure how to that. I mean there is no information regarding BT832X if it is set by default in Master mode, or Slave mode. As well if it is in Slave mode, which address shall I use to send commands? As well, which is the default communication speed (100 kHz or 400 kHz)
What I want to achieve is to send the configuration commands (AT ones) through I2C instead of UART.
Pllease can you tell me the default configuration of it,and of course if it is possible to configure ghe device through i2c?
Thank you in advance
