After processing a received SMS, I want to delete it from the SIM with the means of
adl_atCmdSend(“AT+CMGD=1\r\n” , NULL, NULL);
However, the message was not deleted.
Not being sure, if the command needet to be subscribed before use, I did so in advance with
adl_atCmdSubscribe(“AT+CMGD” ,NULL, ADL_CMD_TYPE_PARA |ADL_CMD_TYPE_ACT);
but without any effect.
What prefents the deletion of SMS #1 on the SIM?
