## Converting Broadlink IR codes to Tasmota
Broadlink is another popular device to send and receive IR/RF codes. Unfortunately, it does not run ESP8266, so it cannot be Tasmotized.
Broadlink codes come either in Base64 format or in Hex format. Below will use Hex format which is easier to work by hand.
Example:
`"Code":`<br>
`"2600700000015692171117111612171116121612161117111735173517361636161117351735173517111636161216121611171116121612163616111735173517351735173517351700053D0001554916000C4E0001554916000C4E0001564817000C4D0001564917000C4C0001564917000D050000000000000000",`<br>
`"Base64":`<br>

The Broadling protocol is described here: [Broadlink RM2 network protocol](https://github.com/mjg59/python-broadlink/blob/master/protocol.md)
Here is a copy of the part specifically describing
|Offset|Contents|
|------|--------|
|0x00|0x26 = IR, 0xb2 for RF 433Mhz, 0xd7 for RF 315Mhz|
|0x01|repeat count, (0 = no repeat, 1 send twice, .....)|
|0x02-0x03|Length of the following data in little endian|
|0x04 ....|Pulse lengths in 2^-15 s units (µs * 269 / 8192 works very well)|
|....|0x0d 0x05 at the end for IR only|
Each value is represented by one byte. If the length exceeds one byte then it is stored big endian with a leading 0.
Example: The header for an Optoma projector is 8920 4450<br>
8920 * 269 / 8192 = 0x124<br>
4450 * 269 / 8192 = 0x92<br>
... which would be encoded as `0x00 0x1 0x24 0x92` in broalink format.
You have all the needed information to convert from Broadlink to Tasmota...
