Hello,
I've tried to implement a custom service with a custom chacteristic, that shows the values per notification in the MCP (Master Control Panel) in percentage.
I played around with the ble_gatts_char_pf_t structure, provide the unit with the value proposed here:
0x27AD | percentage | org.bluetooth.unit.percentage |
but without luck.
.format = BLE_GATT_CPF_FORMAT_SINT8;
.exponent = 1; // ???
.unit = 0x27AD
.name_space = BLE_GATT_CPF_NAMESPACE_DESCRIPTION_UNKNOWN; // tried also: BLE_GATT_CPF_NAMESPACE_BTSIG
Is there any example, which shows, how to setup this structure properly?
It should finally works like the battery level (which is handled in bas.c).
I can see the changeing values during received notifications in MCP, but only as hex value.
Where did I go wrong here?
Thnaks in advance.
Regards Thomas
