I’m new to WS6318 and started working on this recently. Till now I hv successfully made my module ON but i’m not getting SIM_Vcc voltage,it is always at 0V.I’m using 6 pin sim.Also I’m confused abt SIM_PRES pin .I don’t understand whether to connect to Vcc_2V8 or to SIM_Vcc.
In the beginning I tried connecting the SIM_PRES to Supply (3.5V with pull up) and Gnd with pull down ,so do I hv damage the WS6318 though in datasheet they have mentioned that min voltage is 2.4V.
Please help me in sorting out this problem .
thanks in advance.
