Hi Filipe, Vasile, I would recommend using the serial libraries that work on an interrupt basis like serial_hw_int_cts.jal. Using this library with a big enough buffer will prevent that you miss any characters.
I used this - using AT commands - in the libraries bluetooth_hc05.jal and bluetooth_hc06.jal as to be able to check if an OK was received after an AT command. Kind regards, Rob ________________________________ Van: [email protected] <[email protected]> namens vsurducan <[email protected]> Verzonden: zaterdag 3 december 2022 11:09 Aan: [email protected] <[email protected]> Onderwerp: Re: [jallib] Re: Variable Table Append Oh, understood. Reading needs to have priority. Use interrupts then...or avoid using any delays in your actual code. A sms has not an instant execution ( most of the time). So using low speed transmission/reception it might be a working solution.

Current problem is GSM modem seems to acknowledge (ex: "OK") faster than my code can read it... A simple "AT" seems to get the "OK" faster than I can read. And I want to get all acknowledges... to not step to next AT command before having sure of "OK" response from the modem. All my AT commands to send an SMS are working ok, if no checking for the acknowledges... Big battle here under going. :D Thank you for your input.

I was never able to use the serial library (interrupts) as is without a slip of one char in received characters order. I've counted chars to solvethe problem.... Depending on your GSM transciever, some delays may be needed between chars and some longer delays between AT commands and chars.

I did not test it (or compiled it) but I assume you get the idea. const word MAX_TIMEOUT = 20_000 const byte MAX_BUFFER = 20 const byte CR = 0x0D const byte LF = 0x0A var word timer = 0 var byte my_buffer[MAX_BUFFER] var byte index = 0 var byte character = 0 -- Read a string. repeat if serial_hw_data_available() then character = serial_hw_data my_buffer[index] = character index = index + 1 end if timer = timer + 1 _usec_delay(100) until (index == MAX_BUFFER) | (character == CR) | (character == LF) | (timer == MAX_TIMEOUT) The string is then in my_buffer (including a CR or LF).

Could you post some sample code please? I think am missing some important details... How can I define a variable buffer? Because this seems not work: var byte received[]=""... Am also struggling to read my modems relies to AT commands... It seems my code is working correctly and after sending the AT command, the readings from serial port seems to point to characters from the sent command... Getting crazy here while in battle with the code... :D Thank you very much.

I normally also add a timeout to the read function so that it does not hang when nothing is received.
