I tried to send AT commands to WISMO218, but i didn’'t receive any “OK” or other response.
Can you tell me if the WISMO218 works with autobaud at initial setup ?
I don’t have seen any comment in the datasheet about baud rate, parity, # of bits …
Thank you so much if you can give me more infos.
L02 doesn’t support ATPSSTKI=2.
Some SIM cards have STK app which run on power-up. It would display some message on UART and expect a response. ATPSSTKI=2 sends an auto response to some STK commands (see AT manual for more details). If this response isn’t sent, the module is blocked and ATD would fail. I am not sure if disabling it with AT*PSSTKI=0 would help, but it is worth a try.
I have the same problem.
My architecture is the following: wismo218 connected to renesas h836064 Serial Control Interface (SCI) as suggestied by the user guide (Document 4111957 Rev 8.1 February 22, 2012 pag. 39 Figure Number 8: two wire connection)
We build some pieces of oru board, some if them work and some don’t, and what I see is that they don’t answer to AT command.
How can I debug?
What is the exact procedure to make the auto baudrate?
