UART Transmit Interrupt Driven api not working perfectly

[Keval Patel]

I have one more problem. When I enable the Tx, the program is not moving out of the callback. and I have to disable the TX manually from callback everytime. The normal flow should be, after the check o TX is complete,  we have to disable the TX. But the program is not behaving in this way.
If you want to check this behaviour, you can do so in my project by observing how I have done it.4527.echo_bot.zip

Hi

The project you sent errors.

Which NCS version you are using?

Which callback you are referring to?

I have to disable the TX manually

Which part of the code is doing this?

after the check o TX is complete

do you mean uart_irq_tx_enable() or uart_tx_ready?

i'm using NCS Version 2.6.0.
In Callback part i disable the irq_tx_disable function before the sending the data using fifo_fill.

As per API i need to call this tx_disable api after i get the uart_tx_complete returns true. but in my case i'm enable the uart_irq_tx  i do not return from my callback without the disable TX_interrupt.
