Difference in class BleScanResult IOS v2.2 to IOS v3

[melt777]

Gooday

I have noticed that my project only compiles successfully up to IOS v2.2. closer investigation show my beacon scan function seems to be no longer compatible. I would like to know why its not compatible with IOS 3.00 and higher

ble scan function below and the error seems to be referenced to

.advertisingData  and .address

where .advertisingData give an error

error: invalid use of member function ‘const particle::BleAdvertisingData& particle::BleScanResult::advertisingData() const’ (did you forget the ‘()’ ?)
496 | String Beacon_name = results[ii].advertisingData.deviceName();//check if the results have an name

and .address gives an error of

error: invalid types ‘[int]’ for array subscript
500 | scanResults[ii].address[5],scanResults[ii].address[4],scanResults[ii].address[3],

my BLE scan function

void scanBleBeacons(){
  BLE.setScanTimeout(50);
  int count = BLE.scan(scanResults, SCAN_RESULT_MAX);
  for (int ii = 0; ii < count; ii++) {
    size_t len = scanResults[ii].advertisingData.get(buf, BLE_MAX_ADV_DATA_LEN);//used to get an entire block of 31 bytes
    String Beacon_name = results[ii].advertisingData.deviceName();//check if the results have an name
    memcpy(buf_copy, buf, sizeof(buf));//make a copy
    //build  a string out of the MAC char array so we can compare to incoming
    sprintf (emMacCharToString, "em_MAC_%02x:%02x:%02x:%02x:%02x:%02x",
                                scanResults[ii].address[5],scanResults[ii].address[4],scanResults[ii].address[3],
                                scanResults[ii].address[2],scanResults[ii].address[1],scanResults[ii].address[0]);
.   
.
.
}// end of scanBleBeacons

any assistance would be greatly appreciated

Unfortunately you will need to change your code for Device OS 3.0.

The BleScanResult used to have directly accessible member variables, but in Device OS 3.0 access methods are required. Thus instead of using scanResults[ii].address[5] you use scanResults[ii].address()[5].

This may well be in connection with the breaking changes referred to in this post

Particle Device OS Updates Thread

Device OS 3.0.0 Release is available in the Web IDE, Particle CLI and Workbench for (Photon/P1/Electron/Argon/Boron/B SoM/B5 SoM/Tracker). Released on April 8th, 2021 Note: This is a Release and may be used for production. Any known issues are likely slated for a future version, see GitHub issues. This is the first release on non-LTS feature development branch (3.x). To learn more about our new LTS release line, read our blog post. You can view information about Device OS versions, upgrades …

For security and consistency reasons advertisingData is not a field anymore but rather a method and hence requires the additional () when called.

snap, Rick was faster.

Thanks Gents, worked like a charm first time round.

amended code below for reference

void scanBleBeacons(){
  BLE.setScanTimeout(50);
  int count = BLE.scan(scanResults, SCAN_RESULT_MAX);
  for (int ii = 0; ii < count; ii++) {
    size_t len = scanResults[ii].advertisingData().get(buf, BLE_MAX_ADV_DATA_LEN);//used to get an entire block of 31 bytes
    String Beacon_name = results[ii].advertisingData().deviceName();//check if the results have an name
    memcpy(buf_copy, buf, sizeof(buf));//make a copy
    //build  a string out of the MAC char array so we can compare to incoming
    sprintf (emMacCharToString, "em_MAC_%02x:%02x:%02x:%02x:%02x:%02x",
                                scanResults[ii].address()[5],scanResults[ii].address()[4],scanResults[ii].address()[3],
                                scanResults[ii].address()[2],scanResults[ii].address()[1],scanResults[ii].address()[0]);
    //make sure its a eddystone TLM beacon
.

.}//end of function
