Advanced parameters and commands

Pearleye Technical Manual V2.0.0

The command Q=<p8> is used to transmit files to the module. <p8> is an 8 bits

wide parameter value in ASCII hexadecimal notation. It specifies the number for

the file to be created or overwritten. After confirmation of the command by

sending a carriage return character [CR] additional parameters will be

expected; e.g. the type of the file, its size and also the data itself.

Below you will see an example of a character sequence. It creates a file under

the number 16 (0x10) with file type 66 (0x42) containing the text “Testtext” as

data:

Example

>Q=10[CR]

N00000007S4200[PAUSE]D5465737474657874

As from confirmation of the command Q with [CR] the following characters

are not echoed back as usual. That means that the control character sequence

N00… has to be send blind.

The character sequence is divided into the following parts:

Caution



The commands d=<p8> and Q=<p8> do not need additional

confirmation.

Files below ID 0xF0 are not write-protected and thus are

modified or deleted without warning.

The upload via the inband Device Port Serial 0 can take a lot of

time (only some thousand bytes/minute).

For bigger files we recommend to use the external RS232 port

or the inband Device Port Bulk 0.

For details on how to configure the port see

Chapter Baud rate (s) on page 55.

Part Description

Nnnnnnnnn n = file size in bytes – 1.

Creating a file of size 0 is not specified.

Sttmm t = file type (any between „01“ and „FE“)

m = transmit mode (always „00“)
