I'm currently working on a project whose purpose is to allow the maximum of bluetooth mobile phoness users to control a software. To make it, I thought I could use AT commands, making the phones send the codes of the keys pressed thanks to the AT+CMER command. But testing different models of phones, I didn't manage to do it with with the Nokia ones by using AT+CMER. So, is it really impossible to do it this way ? Is there another AT command I could use to retrieve the keys pressed ?
