This section will detail key differences between firmware releases of the LT2510. The previous sections of the User
Manual only deal with the latest version. Some features and default settings have changed from one firmware to
the next. This section will detail those differences.
Hardware changes:

FW1.2-5
FW1.4-1
FW1.5-0
FW1.6
On PCB 00157 Rev 0 and Rev 1, the FCC ID is KQL-2510100 and the IC number is 2268C-2510100
On PCB 00157 Rev 2, pin 13 at the connector was swapped with pin 20.
On PCB 00157 Rev 2 and forward the FCC ID is KQL-2510100P and the IC number is 2268C-2510100P
• Initial Release.
• This version has an issue which permits received RF packets that fail CRC check to be forwarded across the UART.
• This version has an issue which permits a Client RF packet to collide with a Server RF packet in Full Duplex mode.
• Baud rates <= 4800 baud will drop a byte when sending packets over the serial interface larger than the RF Packet Size.
• The Bin Analyzer command reports the incorrect bin number.
• The module does not work properly below 0°C.
• CRC issue present in 1.0-3 was corrected. This correction makes a v1.0-3 radio incompatible over the air with any newer versions of the Firmware.
• Fixed Full Duplex Mode issue.
• Changed Deep Sleep AT Command from CC 86 003 to CC 86 03 00 00 00. The new command is backwards compatible, but the old command
• RF Data Rate (EEPROM bytes 0x51-0x53) has been superseded by the RF Profile byte (EEPROM 0x54). RF Profile is the preferred method to set
• Reduced RX Buffer from 768 bytes to 512 bytes and increased the heap memory to 1800 bytes. All serial and RF packets are now routed through
• 9-bit mode released.
• Fixed issue with baud rates <=4800.
• Fixed issue with temperatures below 0°C
• Serial firmware upgradeability feature was added. Firmware versions prior to v1.4 do not support field upgradeability.
• Reset radio and restore factory defaults command (0xCC 0xFF 0xDF) was added. This command will reload the factory default EEPROM command.
• Added profile 0x03 (280kbps RF data rate, 43 hops). This profile is legal for both FCC and CE markets. Profile 0x02, which also supports 280kbps
• Prior to this release, Auto Config could only correctly set Interface Timeout if a standard baud rate was used. Selecting non-standard baud rates
• Added RS-485 Driver Enable control pin.
• Added RSSI functionality to the PWM output pin.
• Added Vendor ID.
• Prior to this release, pin 13 (GI_0) was configured as an output. It is now an input.
• Added 485 DE-RE to Auto Config. If Auto Config is disabled, 485 DE-RE Delay must be set manually.

the heap. CTS_ON and CTS_Off only reflect the memory usage of the 512 byte RX buffer. The RX buffer will never fill unless the heap becomes full.
and 43 hops, is only permitted in FCC markets. The two profiles are not over the air compatible with each other.
required Auto Config to be disabled and Interface Timeout to be set by the user. This version and forward, Interface Timeout can set by the radio
regardless of baud rate selection, provided Auto Config is disabled.
