QUESTION
I'm using the SiliconLabs's BGLIB static library for comunicate via SerialPort, with BLED112. For use this library it's necessary to define two function: one for send and another for receive bytes to and from SerialPort. All data received from serial can be divided in two part: header and data.
Following the "main.c" code of "thermometer-demo" example the function that receive data from serial, receive first of all header and than data. When the header and data has been received, the code parse the header by follow code and initialize a *msg
variable:
ANSWER
Answered 2018-Jan-18 at 08:42I have contacted SiliconLabs support and that the original libraries are correct and it seem I have a incorrect version of the libraries.
Like the SiliconLabs support suggest me (and like explained very good in this link: http://www.drdobbs.com/questions-answers-creating-variable-siz/184403480), there are 3 possible kind of declarations:

QUESTION
I am using the BGLib in my Qt application to communicate over BLE.
In the main thread the GUI is running (sensornode_gui.cpp). By clicking on a pushButton a different thread starts to scan for BLE devices (ble_connection). I get the resulting information from a callback function such as void ble_evt_gap_scan_response(const struct ble_msg_gap_scan_response_evt_t *msg)
. How can I emit signals from that callback function to update the GUI with some attributes from msg
for example?
main.cpp
...ANSWER
Answered 2017-Jan-20 at 21:00You May declare a global variable in "ble_connection.h"
QUESTION
I am using a BLE121LR module to construct an Eddystone beacon. I am aware of the overall BLE related advertisement use cases and advertisement packet format for Eddystone as well. I know Eddystone packet does not contain device (friendly) name.
I have set up the beacon advertisement using API:
...ANSWER
Answered 2017-Oct-21 at 11:53It isn't possible to advertise the name of the beacon since there is no room in the advertising packet. The intent with Eddystone is that the advertised URL is the means of identification. You could try using multiple advertisements. Use a timer to control switching between the Eddystone beacon and another advertisement which does contain the device name.
