codeless: increase storage of a characteristic

Hi,

CodeLess has no extended command that supports the format you are using. The ATI (or ATrI when used as a remote command) is a non-extended command (meaning it does not feature a '+' ). ATI is supposed to be used as a request to return a set of characters identifying the hardware and software of the physical device. Did you implement your own extended command in CodeLess?

If you want to send data over Bluetooth using already defined commands in CodeLess, you should use either the

ATr+PRINT=

or the simplified version using the '|' or "pipe" character:

|

Both of these commands require that you are in a Bluetooth connected state when the command is issued.

CodeLess uses sprintf to generate some of the responses which limits the response length to 255 characters. You can safely expand CodeLess to handle 255 characters following the instructions provided below. You should ensure that the remote end (in your case the smartphone app) responds either 'OK' or 'ERROR' to every data transmission from your microcontroller. Unless you use the "pipe" command as described above, CodeLess will expect to receive a reply from the remote end before it is ready for the next transmission and you may not be able to send any new data until a reply has been received. Using the "pipe" command removes the need for a reply.

Here is how you can change the implementation to support 255 characters:

In da1458x_config_basic.h:

Add a define

#define CMD_BUFFER_SIZE 255

(Moving the define to this file allows us to access it globally)

In user_cmd_parser.h:

Out-comment the old define

#define CMD_BUFFER_SIZE 160

Like this

//#define CMD_BUFFER_SIZE 160

In the same file, change:

#define CMD_MAX_ARG_LENGTH 160

to

#define CMD_MAX_ARG_LENGTH CMD_BUFFER_SIZE

In user_custs1_def.h

Change

#define DEF_CUST1_INBOUND_LEN 160

To

#define DEF_CUST1_INBOUND_LEN CMD_BUFFER_SIZE

And, in the same file, change

#define DEF_CUST1_OUTBOUND_LEN 160

To

#define DEF_CUST1_OUTBOUND_LEN CMD_BUFFER_SIZE

In the extract_args() function of the user_cmd_parser.c file

Change

for(uint8_t i=0;i< 160 ;i++)

to

for(uint32_t i=0;i< CMD_BUFFER_SIZE ;i++)

In the uart2_rec_data_avail_isr() function of the user_uart2.h file

Change

if(readData == 0x0D || bytesIn > 150)

to

if(readData == 0x0D || bytesIn > CMD_BUFFER_SIZE)

In codeless_env_t struct of the user_cmd_interpreter

Change

char current_cmd[160];

to

char current_cmd[CMD_BUFFER_SIZE];

You can change the CMD_BUFFER_SIZE to 512 (I did not test this), but all the replies from CodeLess will be reduced to 'OK' or 'ERROR'
