Hi everyone,
I use the SL8082BT with two SIM cards.
At one time, switching algorithm I discussed on the SW forum ,
https://forum.sierrawireless.com/t/dual-sim-for-sl8082/6786/5
and it is perfectly
worked with SL8082 modules. Now with SL8082BT stopped working.
The behavior of the two modules in this algorithm:
SIMLPM=2 option is set (at!custom=“SIMLPM”,2)
Module works with the first SIM card at power on.
------ SL8082 -----
- at + cfun = 4
output VREG_USIM remains high - at!dio = 1,1
switching between SIM interface occurred, VREG_USIM some time
remains on, then proceeds to zero. - at + creg = 1,0
VREG_USIM quickly switched on and the module starts with
second SIM card
Checking at!iccid? confirms switching to second SIM.
------ SL8082BT -----
- at + cfun = 4
output VREG_USIM remains high - at+wiow = “GPIO1”, 1
switching between SIM interface occurred, VREG_USIM some time
remains high, then proceeds to zero. - at + creg = 1,0
VREG_USIM power does not turn on
Checking at!iccid? naturally gives ERROR.
Each SIM interface individually working fine. Does not work
switching algorithm only. To switch SIMs FSA2567MPX is used.
And yet, when exiting LPM should not be software reset, because the sim selection is performed directly gpio1.
Any ideas on this subject
