CR95HF UART communication

Hello,

I am writing this post because i have a problem with UART communication. I am using à microcontroller in order to communicate with the CR95HF chip but i can't have any response even when i'm sending an echo command. However, both pins SSI_0 and SSI_1 are connected to the ground and i'm pulling down the UART_RX/IRQ_IN more than 10us after i powered up the CR95HF chip as it's written in the datasheet.

I figured out a problem, my UART_TX/IRQ_OUT pin is always at 0V, but even if i link a pull-up resistor, i still have no answers.

Can anyone help me with my problem? i would really appreciate.

Best regards
