Specifying Client Address

Hello, first of all thanks for making and maintaining the library. I would like to connect to a specific BLE beacon. Currently I am using this command and it's working perfectly: pClient = NimBLEDevice::createClient(NimBLEAddress("49:42:06:00:20:4e")); However, if I substitute it with a variable I get the error: no matching function for call to 'NimBLEAddress::NimBLEAddress(String)'. This is the code: pClient = NimBLEDevice::createClient(NimBLEAddress(String(value)));

Can the command accept such values or must it be specified like in the first case?

Any help would be appreciated! Kind regards, Mia

I've managed to resolve the error by using an integer: pClient = NimBLEDevice::createClient(NimBLEAddress(value.toInt()));, however, it also truncates the address from 49:42:06:00:20:4e to 49. Do you know what could be the solution?

Hi @miag676, the NimBLEAddress constructor takes a std::string parameter. If you change the code in the first post to std::string(value) instead of String(value) it should work.

Thanks for your response! I tried using it like this: pClient = NimBLEDevice::createClient(NimBLEAddress(std::string(value)));, but get the following error: no matching function for call to 'std::__cxx11::basic_string::basic_string(String&)'. Did I write anything wrong in this line of code?

Try this: NimBLEDevice::createClient(NimBLEAddress(std::string(value.c_str())));

A std::string needs a char* for initialization

Thank you very much. This solved the issue!
