this is what the code posted in the link you gave does. The actual values is only 6 bytes long if I remember well, so it’s a matter of reading each byte individually and converting into its ASCII hexadecimal representation.
#Convert mac address to hex values how to
The compiler does not know how to convert those into Strings or cStrings, so you need to do this yourself.
#Convert mac address to hex values 64 bits
You use a 64 bits (8 bytes) long integer. arduino powers up and sends a broadcast message via xbee-api RPi receives the xbee broadcast packet (via an asynchronous python script) and sends a unicast message back to the MAC address of the. I'm new to C so please pardon my lack of understanding. When you do something like uint64_t espChipID = ESP.getEfuseMac() Hi there, I'm having a heck of a time converting a MAC address to a uint32t value. I won’t comment on the use of the String class, you know the pitfalls. What is clientHTTPMagicMirror? which library is being used? is there a way to post params independently? what is postAttributeFirmware, firmwareCode etc ? They are likely Strings indeed ut don’t post snippets ( Snippets R Us!) I found one possible lead with this code ( ) but I don't understand it well enough to know how to adjust it to input ESP.getEfuseMac() and get out a string called efuseMac.Īny help or pointers in the right direction would be appreciated. 51K Announcement: We just launched math tools for developers. Just paste your IP address in the form below, press the Convert to Hex button, and you'll get an IP in the hexadecimal base.
Unless someone can suggest another workaround, I think I need efuseMac and wifiMac to be strings as well. World's simplest online IP to hexadecimal converter for web developers and programmers.
You can do this vice versa or any mode you want. I'm no expert, but I believe this is concatenating a bunch of string to form the post. If you want to convert MAC Addresses to Hexadecimal value, you can use Windows Calculator< change it to scientific mode then choose Hex then type in the Hex value, and then choose Dec mode. String payloadMagicMirror = clientHTTPMagicMirror.getString() The MAC Address represents a unique number that helps in identifying any device. The code for sending the data is: int returnCodeMagicMirror = clientHTTPMagicMirror.POST( postAttributeFirmware + firmwareCode + postAttributeEfuseMac + efuseMac + postAttributeWiFiMac + wifiMac + postAttributeSensorID + sensorID + postEnd ) The MAC Address on the bar code label is 00:04:F1:AF:49:1F Convert MAC Address to the hexadecimal representation of Tag ID is 0x02AF491F The Tag ID in decimal. A 64-bit interface ID is created by inserting the hex value of FFFE in the middle of the MAC address of the network card. To convert a hex number to denary, multiply each digit with its value. My Arduino (technically an ESP32) sends some json data to my MagicMirror using HTTP POST. I'm pretty sure that someone is going to say, "Why are you doing this? You shouldn't use a string." So here's my situation: My basic question is how can I convert the units MAC address (from ESP.getEfuseMac() and/or WiFi.macAddress() ) into a string?
