Hello All:
I am new to the LIRC list.
After going through the LIRC community for solution and trying all the suggestions, I tried to go through source code.
I am trying to replace the IR sensor and IR transmitter between RPI3 and an HDMI switch (lirc.conf generated using irrecord is attached).First I tested the codes over IR. works fine.
Here is the list of IRSENDs from one RPI3 using the IR and the corresponding bit string received by the another RPI's IR sensor.

irsend SEND_ONCE DOCKTALK PIP
binaryString[67]: 100000000111111110011000011001111

irsend SEND_ONCE DOCKTALK PORT1
binaryString[67]: 100000000111111110000001011111101

irsend SEND_ONCE DOCKTALK PORT2
binaryString[67]: 100000000111111111110000000011111

irsend SEND_ONCE DOCKTALK PORT3
binaryString[67]: 100000000111111111001000001101111

irsend SEND_ONCE DOCKTALK PORT4
binaryString[67]: 100000000111111111001100001100111

irsend SEND_ONCE DOCKTALK PORT1
binaryString[67]: 100000000111111110000001011111101

irsend SEND_ONCE DOCKTALK OK
binaryString[67]: 100000000111111111010100001010111

irsend SEND_ONCE DOCKTALK PORT1
binaryString[67]: 100000000111111110000001011111101

I tried to use the invert=1 and softcarrier=0 options after replacing the IR TX/RX between two RPI's GPIO pins with SIG and GND wires. No success.
Then I thought to replace the toggle_bit_mask in the lirc.conf file:
# toggle_bit_mask 0x0
toggle_bit_mask 0x0001FFFFFFFFFFFFFFFF

irsend give an error. not recognizing DOCKTALK.
Any guidance you may provide would be greatly appreciated.
Thank you for your help.
Regards,Raj
