Sim remote HL series

Hi all,

I have a question regarding SIM REMOTE (rSAP) functionality using HL series.

I saw there is an AT command (AT+KSAP) to enable it, but I would like to ensure what is behind this command.

I’m not sure to understand, but this command permits to use a SIM which is in an external device using Bluetooth or another way ?

I mean the link with the SIM connector is deactivated ?

Thanks in advance if anybody could help me.


Moved to the correct section


which module are you using? which command guide are you referring to? can you share the link?



I’m talking about this document : … ification/

+KSAP command seems to enable/disable rSAP, but I’m not sure to understand if this feature allows the modem to use a SIM via Bluetooth, or whatever except the standard SIM connector.

Thanks if you could help me.

PS : I’m not using any module, I’m looking for a module using rSAP.

I don’t have Hilo module to test here…
But when I go through the doc you shared, it seems like some functionality relate to CMUX feature of Hilo.

Also i found similar discussion [url]]



as HL series could use rSAP feature I could use it on MangOh Platform using Legato AP to configure rSAP and simulate a SIM.

Thanks for your answer.
