4) Set module parameters: programming user parameters
uint8_t *buffer;
buffer[0] = 32;
buffer[1] = APP_SERVICE_FRAME;
buffer[2,3] = target_module.group;
buffer[4,5,6,7] = target_module.address;
buffer[8] = SERVICE_PARAM_SET;
buffer[9] = PROG_GRP_USER_DATA;
buffer[10 -> 29] = *user_data_buffer;
buffer[30,31] = CRC16;
5) Get module parameters
uint8_t *buffer;
buffer[0] = 12;
buffer[1] = APP_SERVICE_FRAME;
buffer[2,3] = target_module.group;
buffer[4,5,6,7] = target_module.address;
buffer[8] = SERVICE_PARAM_GET;
/* FOR GET DATA LINK STACK PARAMETERS */
buffer[9] = PROG_GRP_LL_STACK_PARAM;
/* FOR GET MODULE PARAMETERS */
buffer[9] = PROG_GRP_DEVICE_DATA;
/* FOR GET USER DATA */
buffer[9] = PROG_GRP_USER_DATA;
buffer[10,11] = CRC16;
After a certain delay from the get command acknowledgment, the PLM module will send the following
frame:
/* RESPONSE FRAME FOR DATA LINK STACK PARAMETERS GET COMMAND */
APP_userdata_t frame;
frame.source = SOURCE_PLM / ...; // Data source PLM, ...
frame.type = APP_SERVICE_FRAME;
frame.len = 52;
frame.error = APP_ERROR_NONE;
frame.broadcast = FALSE;
frame.group = sender.group; // Device (the one been queried)group
frame.address = sender.address; // Device (the one been queried)address
frame.data[0] = SERVICE_PARAM_GET; // Command echo

frame.data[38,39,40,41] = PLM_NTW_P_FRM_RX_TO; // Timeout for frame receptions
frame.data[42,43,44,45] = PLM_NTW_P_NDX_TO; // Minimum delay before any
frame.data[46,47] = PLM_LL_MAX_ATTEMPT; // Max attempts if no activity is detected
frame.data[48,49] = PLM_LL_MAX_RPT_ATTEMPT; // Max repetition attempts (processed ID)
