It seems like I can't add a new characteristic to a service in Bluetooth Low Energy. I am programming based on the Simple Peripheral example, which has 5 characteristics. I want to add a 6th and 7th characteristic, based on how the other 5 characteristics are initialised in the simple_gatt_profile.c and .h. When I do that, the code doesnt work anymore, It seems to be hanging somewhere after calling the bios_start() in main. The tasks dont get called. So there must be something wrong with the way I create the characteristics. Here is some code: From the simple_gatt_profile.h:
// Profile Parameters
#define SIMPLEPROFILE_CHAR1 0 // RW uint8 - Profile Characteristic 1 value
#define SIMPLEPROFILE_CHAR2 1 // RW uint8 - Profile Characteristic 2 value
#define SIMPLEPROFILE_CHAR3 2 // RW uint8 - Profile Characteristic 3 value
#define SIMPLEPROFILE_CHAR4 3 // RW uint8 - Profile Characteristic 4 value
#define SIMPLEPROFILE_CHAR5 4 // RW uint8 - Profile Characteristic 5 value
#define SIMPLEPROFILE_CHAR6 5 // RW uint8 - Profile Characteristic 6 value
#define SIMPLEPROFILE_CHAR7 6 // RW uint8 - Profile Characteristic 7 value
// Simple Profile Service UUID
#define SIMPLEPROFILE_SERV_UUID 0xFFF0
// Key Pressed UUID
#define SIMPLEPROFILE_CHAR1_UUID 0xFFF1
#define SIMPLEPROFILE_CHAR2_UUID 0xFFF2
#define SIMPLEPROFILE_CHAR3_UUID 0xFFF3
#define SIMPLEPROFILE_CHAR4_UUID 0xFFF4
#define SIMPLEPROFILE_CHAR5_UUID 0xFFF5
#define SIMPLEPROFILE_CHAR6_UUID 0xFFF6
#define SIMPLEPROFILE_CHAR7_UUID 0xFFF7
// Simple Keys Profile Services bit fields
#define SIMPLEPROFILE_SERVICE 0x00000001
// Length of Characteristics in bytes
#define SIMPLEPROFILE_CHAR1_LEN 20
#define SIMPLEPROFILE_CHAR2_LEN 20
#define SIMPLEPROFILE_CHAR3_LEN 20
#define SIMPLEPROFILE_CHAR4_LEN 20
#define SIMPLEPROFILE_CHAR5_LEN 20
#define SIMPLEPROFILE_CHAR6_LEN 20
#define SIMPLEPROFILE_CHAR7_LEN 14
And from simple_gatt_profile.c:
// Simple GATT Profile Service UUID: 0xFFF0
CONST uint8 simpleProfileServUUID[ATT_BT_UUID_SIZE] =
{
LO_UINT16(SIMPLEPROFILE_SERV_UUID), HI_UINT16(SIMPLEPROFILE_SERV_UUID)
};
// Characteristic 1 UUID: 0xFFF1
CONST uint8 simpleProfilechar1UUID[ATT_BT_UUID_SIZE] =
{

};
// Characteristic 2 UUID: 0xFFF2
CONST uint8 simpleProfilechar2UUID[ATT_BT_UUID_SIZE] =
{
LO_UINT16(SIMPLEPROFILE_CHAR2_UUID), HI_UINT16(SIMPLEPROFILE_CHAR2_UUID)
};
// Characteristic 3 UUID: 0xFFF3
CONST uint8 simpleProfilechar3UUID[ATT_BT_UUID_SIZE] =
{
LO_UINT16(SIMPLEPROFILE_CHAR3_UUID), HI_UINT16(SIMPLEPROFILE_CHAR3_UUID)
};
// Characteristic 4 UUID: 0xFFF4
CONST uint8 simpleProfilechar4UUID[ATT_BT_UUID_SIZE] =
{
LO_UINT16(SIMPLEPROFILE_CHAR4_UUID), HI_UINT16(SIMPLEPROFILE_CHAR4_UUID)
};
// Characteristic 5 UUID: 0xFFF5
CONST uint8 simpleProfilechar5UUID[ATT_BT_UUID_SIZE] =
{
LO_UINT16(SIMPLEPROFILE_CHAR5_UUID), HI_UINT16(SIMPLEPROFILE_CHAR5_UUID)
};
// Characteristic 6 UUID: 0xFFF6
CONST uint8 simpleProfilechar6UUID[ATT_BT_UUID_SIZE] =
{
LO_UINT16(SIMPLEPROFILE_CHAR6_UUID), HI_UINT16(SIMPLEPROFILE_CHAR6_UUID)
};
// Characteristic 7 UUID: 0xFFF7
CONST uint8 simpleProfilechar7UUID[ATT_BT_UUID_SIZE] =
{
LO_UINT16(SIMPLEPROFILE_CHAR7_UUID), HI_UINT16(SIMPLEPROFILE_CHAR7_UUID)
};
