One other thing forgot to mention You might try to use this command AT^CURC? Current setting of periodic status messages AT^CURC=? See what you possible values are AT^CURC=0 turn off periodic status messages
This should control the output of ^BOOT ^RSSI ^MODE ^DSFLOWRPT ^CONN ^CEND ^CONF ^ORIG ** Your device may or may not have some messages and may depend on the connection mode. You can still retrieve RSSI using AT+CSQ There is also Singnal to Noise Ratio AT^CSNR? Just for completeness 'GPRSONLY' : 'AT^SYSCFG=13,1,3FFFFFFF,2,4', '3GONLY' : 'AT^SYSCFG=14,2,3FFFFFFF,2,4', 'GPRSPREF' : 'AT^SYSCFG=2,1,3FFFFFFF,2,4', '3GPREF' : 'AT^SYSCFG=2,2,3FFFFFFF,2,4', This relates to SYSCONFIG SYSMODE / ^MODE messages '0,0' : notifications.NO_SIGNAL, '3,2' : notifications.GPRS_SIGNAL, '3,3' : notifications.GPRS_SIGNAL, '5,4' : notifications.UMTS_SIGNAL, '5,5' : notifications.HSDPA_SIGNAL, '5,6' : notifications.HSUPA_SIGNAL, '5,7' : notifications.HSPA_SIGNAL, AT^SYSINFO On Jan 17, 11:31 am, nxnlvz <nxn...@gmail.com> wrote: > I have several of the Huawei modems as well.
