Table 141413: RF Function Status
3.9.2.3.11.2. W_DISABLE2#*
RM500Q-AERM500Q-AE&RM502Q-AE module provides a W_DISABLE2# pin to disable or enable the
GNSS function. The W_DISABLE2# pin is pulled up by default. Driving it low will disable the GNSS
function. The combination of W_DISABLE2# pin and AT commands can control the GNSS function.
Table 151514: GNSS Function Status
A simple level shifter based on diodes is used on W_DISABLE1# pin and W_DISABLE2# pin which are
pulled up to a 1.8 V voltage in the module, as shown in the following figure. So the control signals (GPIO)
of the host device could be aat 1.8 V or 3.3 V voltage level. W_DISABLE1# and W_DISABLE2# are active
low signals, and a reference circuit is shown as below.
