On a HiloNcV2 / HL6528RD, I use 4 virtual links via gsmMuxd.
Due to an HL6528RD bug, the modem hang up my GPRS connection on mux 4 when I hang up a phone call on mux 2. Thus my program has often to redial using ATD99# to recreate the GPRS connection.
This brings me to the burning issue that sometimes I have to do a voice call using ATD on MUX2 while MUX4 ATD99# to recreate the GPRS connection. This creates errors either on MUX2 or MUX4
It could be “timeout” of ATD*99# on Mux4 or/and MO call setup issue on Mux2.
Could you confirm that we cannot use ATD for voice call and ATD99# for initiation GPRS at the same time?
If so, should I allow a voice call again just after receiving CONNECT from ATD99#? When should I allow ATD*99# after a voice call, on hang UP?
Thanks in advance
