Diagnostics
Diagnostics Commands
AT
Name and Description
Command
VR Firmware Version. Read firmware version of the module.
HV Hardware Version. Read hardware version of the module.
RF Errors Read the number of times we found the end of a valid preamble with a valid
ER hopping sequence and a valid packet type and some kind of error occurred in reading
the rest of the frame. When the value reaches 0xffff, it stays there.
Good packets Read the number of good frames with valid MAC headers that are
GD
received on the RF interface. When the value reaches 0xffff, it stays there.
RC RSSI for channel Reads the DBM level of the designated channel.
