I've tried them all: NRF24L01, 315MHz/433MHz modules, HC05 Bluetooth, PS2, HC12, all with varying success. I liked HC12 because it was only 2 wires, vs NRF24L01 with 8 (if you use the interrupt), but had LOTS of problems with continuity and I'm only transmitting across my desk. (I tried bigger separation, 10 feet, no difference except I walked more). So which one is best for wireless, say between a joystick and a robot?

I am working with Arduino on a ESP32 TTGO mini board and I would like to broadcast, via WiFi, GPS coordinates to a simple iPAD (in situations where Cellular connectivity is non existent) to display those live coordinate positions on an Map APP, ie. US Forest Trails Map, etc. I have followed the Getting Started with WiFi video and have successfully connected via WiFi from the ESP32 board (as an Access Point and my iPAD as a Station); now I need help actually broadcasting realtime GPS coordinates to my iPAD MAP to display my actual position.

@do_not_give_up Have ypu tested the range of the esp32 wifi? Without an external antenna it might be 20 ft, with an antenna maybe a few dozen feet.
As far as your next step, just get Bill's (DroneBotWorkshop) GPS video/blog and that will show you how to display your position in Google Map.
Arduino says and I agree, in general, the const keyword is preferred for defining constants and should be used instead of #define

Thanks for your reference Ron, what is the exact title of Bill’s suggested YT video?
I have been able to utilize the WiFiAccessPoint.ino
to pass live GPS data to a webpage. However, I must manually reload/refresh the webpage to view the updated data?

@do_not_give_up I am of the school 'teach them how to fish', so Bill's video is found by going to his channel and searching WITHIN his channel for GPS. The videos are great eye candy, but for learning shrink the video, under the video is a 'more' button, the first line after that is generally 'Article with code samples'
As to the refresh issue, you could try using the browser tab periodic reload or words to that effect for your browser of choice, mine is a chrome clone called Vivaldi but any decent browser will have the equivalent.

@do_not_give_up I did a google of 'html to cause web page to refresh' and got a few answers, most were useless, but a couple looked doable. I don't know html at all, I am an old tube guy, and even transistors are something of a mystery to me. I rely on google, and 'beneficial wishful thinking'.
