Issue with I2C Communication on Nucleo-L452RE: Master and Slave Indicate BUSY State

Hello,

I am currently working with I2C communication using the Nucleo-L452RE board. I am encountering an issue where:

  1. The master device indicates that the slave is busy receiving.
  2. Simultaneously, the slave device indicates that the master is busy receiving.

I have double-checked the configuration for both devices and ensured that the pull-up resistors are correctly connected. Despite this, the communication remains stuck in a busy state.

Here are some additional details about my setup:

  • Microcontroller: STM32L452RE
  • I2C Role: Master (Nucleo-L452RE), Slave (Nucleo-L452RE)
  • Pull-Up Resistors: [Specify values, e.g., 4.7 kΩ]

I would appreciate any insights or suggestions to resolve this issue. If more details or specific configurations are required, please let me know.

Thank you in advance for your help!
