[SOLVED] dsPIC33EP64MC204 RDA Interrupt

Good, you move forwards.
But, still nothing added to limit the value of buffer_ind. This really must be
handled.

Nice that you solved your problem :-). But you'll likely run into another problem, if you'll talk with the GSM for long enough. You have to wrap buffer_ind back to 0 when you fill the buffer, otherwise the data from GSM will start overwriting locations above your allocated buffer size.

Yes I know you are right. I've already added it. Thank you for your care. I'm debugging all the time and sometimes I forget to add some lines.

As a comment, 'moving on', I notice you were using software serial
for the RS485 link. Given your chip has a second UART, consider using this.
Otherwise the receive ISR 'risks' resulting in bit width corruption on this
port.

Hmm.. I didn't know. Okay, I will definitely consider it. Thank you very much for sharing your thoughts with me.)
You are number one!
