To change the channel, the setChannel command can be used (assuming nodetest application is on the device).
Table 7 lists the valid parameters to be used with setChannel command.

5.1 EM3x Module Interface Connector
Two single-row, 0.05” pitch, connectors make up the EM3x module interface to the EM35x breakout board. In
addition, two single-row, guide connectors on the EM35x breakout board assist with connecting the EM3x module
to the breakout board. The board-to-board connector scheme allows access to all EM3x GPIO as well as nRESET
and the JCLK signals. The connector is illustrated in Figure 3, while the connector dimensions are listed in Figure 4.
