Configure M2.59 for nRF Low Power Operation
nRF Low Power Operation functionality is enabled by S Register 109.
Make sure the UART is communicating with the nRF by sending the
ati0
command;
Pinnacle 100 =nRF & HL7800 = HL7800
By default, the nRF will be communicating with HL7800 upon boot, to switch to communicate with the nRF, toggle the DTR
check box, on and off, the console should now be switched, but check with ati0. By toggling the DTR signal, the UART will
switch between radios.
Send the following commands to the nRF, to enable the nRF low power operation, save the setting, and reboot. Connect a
jumper from Pin M2.59 to J9 Pin 11. The jumper can be connected to either 1.8V (Low power disabled) [J9 Pin 11] or GND
(Low Power enabled) [J9 Pin 12] depend on the desired operation. See Figure 3
