In the neon-soaked sprawl of Neo-Sampaio, Elias was the city’s most elusive "Data-Drifter," a driver who specialized in high-stakes deliveries that bypassed the digital checkpoints of the ruling tech conglomerates. His secret weapon wasn't the engine of his modified sedan, but a fabled, rogue file known as the .

At its core, (sometimes known for its casting features) is a specialized application frequently used on aftermarket Android car stereos to facilitate phone-to-car connectivity. While official Android Auto runs directly off a connected phone, CarLetter often serves as an interface layer or alternative connection protocol on Android-based head units to seamlessly run smartphone mirroring.

Ensure Google Play Protect is active on your phone. It scans sideloaded apps for known threats.

Length information

The two equivalent length bytes in the telegram header of the variable format contain the number of information bytes in the body of the telegram. These include: DA, SA, FC and the PDU. The value ranges from 4 to 249, so that no more than 246 bytes can be transferred to the PDU of a telegram. No value <4 is allowed, because a telegram must comprise at least one DA, SA ,FC and a data byte. The longest telegram therefore comprises 255 bytes overall.

The FCS (Frame Check Sequence) checksum required in the telegram for Hamming distance 4 is always located directly in front of the end delimiter (ED) and has the following configuration:

7	6	5	4	3	2	1	0
0 to 255								Checksum

For the without-data format (SD1) the checksum must be formed by the arithmetical sum of DA, SA, and FC without start delimiter (SD) or end delimiter (ED) and disregarding sums carried over. For the fixed length format with data (SD3) and the variable length format (SD2) the checksum must also include the payload (PDU). Example of bytes added together in the FCS:

The two address bytes in the telegram header of telegrams (Request, Confirmation and Response telegrams) contain the station’s destination address (DA) and source address (SA).

7	6	5	4	3	2	1	0	DA: Destination address
	0 — 127 (0x7F)							Destination address
0 1								no DSAP (SAP = NIL) DSAP present

7	6	5	4	3	2	1	0	SA : Source address
	0 – 126 (0x7E)							Source address
0 1								no SSAP (SAP = NIL) SSAP present

Address 127 is reserved as a global address for broadcast or multicast messages (telegrams to all bus users or user groups selected via service access point; only allowed with Send Data with No Acknowledge, SDN). The address byte of the Request telegram should be reflected in the Response telegram in reverse, i.e. the SA byte of the Response telegram contains the destination station address and the DA byte the source station address of the Request. For formats with a PDU, the address extension serves to identify a destination and/or source address extension in the form of a Service Access Point (SAP) that immediately follows the FC byte in the PDU. The address extensions of a Request telegram must be reflected in the Response telegram in reverse. If the address extension bit has not been set, it is the special SAP = NIL. This Service Access Point has the advantage that its telegram is 2 bytes shorter and is therefore used for cyclic data exchange.
