Hi,
I am trying to create a modify the BLE GATT service TXPWR to allow me to
set the power as well as read. Not to spec, but bear with me here.
*1) This works: *
},
[3] = {
/*** Service: TXPWR */
.type = BLE_GATT_SVC_TYPE_PRIMARY,
.uuid128 = BLE_UUID16(GATT_SVR_SVC_TXPWR_UUID),
.characteristics = (struct ble_gatt_chr_def[]) { {
.uuid128 = BLE_UUID16(GATT_SVR_CHR_TXPWR_TXPWRLVL),
.access_cb = gatt_svr_chr_txpwrlvl_cb,
.flags = BLE_GATT_CHR_F_READ,
}, {
0, /* No more characteristics in this service. */
} },
},
{
0, /* No more services. */
},
};
*2) Adding an additional characteristic to this service definition
compiles, but seems to be stuck trying to register services on an internal
loop. *
#define GATT_SVR_CHR_TXPWR_TXPWRLVL_SET 0x2A08
....
},
[3] = {
/*** Service: TXPWR */
.type = BLE_GATT_SVC_TYPE_PRIMARY,
.uuid128 = BLE_UUID16(GATT_SVR_SVC_TXPWR_UUID),
.characteristics = (struct ble_gatt_chr_def[]) { {
.uuid128 = BLE_UUID16(GATT_SVR_CHR_TXPWR_TXPWRLVL),
.access_cb = gatt_svr_chr_txpwrlvl_cb,
.flags = BLE_GATT_CHR_F_READ,
}, {
.characteristics = (struct ble_gatt_chr_def[]) { {
.uuid128 = BLE_UUID16(GATT_SVR_CHR_TXPWR_TXPWRLVL_SET),
.access_cb = gatt_svr_chr_txpwrlvl_cb,
.flags = BLE_GATT_CHR_F_READ,
}, {
0, /* No more characteristics in this service. */
} },
},
{
0, /* No more services. */
},
};
*Here's the output out of the serial port:*
