Miana smith5/7/2023 I did have a false start with that though, in that BLE Scanner listed several services which the RN4871 could do, but it looked like only one of those services would actually communicate back through serial. I typed "test" and "hello" in from the BLE Scanner, and would you look at that, they appeared on my serial connection! It was even more exciting when there was communication between the bluetooth chip and my phone. It was an exciting moment when a bunch of numbers that I don't know how to interpret ran across the screen. miniterm will not necessarily display what you are typing and that's just a little disconcerting. I forgot to call miniterm with a baud rate and couldn't figure out why nothing was happening and 2. The things I did here that were dumb were 1. I also found it concerning that it was listed as having "no services" because this was inconsistent with Neil's video and Rob's tutorial.įrom there, I followed Neil's video and ran miniterm.py to configure the board and then to communicate between it and the phone. I identified it as my board because it had the strongest signal, and that signal would change as I moved around. The above picture shows how it was listed. When I went searching for it, my board just showed up as BLE-A8AC which seems terribly generic. And in the tutorial that Rob linked to, the board shows up named RN4871. In Neil's video, the board shows up named, and I couldn't figure out how to do that. Though the UI is different and tbh kinda worse. This app alledges to have been made by the same people as the identically named Android app that Neil uses in this video. Here's a photo of the board (with LED on!) plugged into my FabFTDI board.Īfter making the board, I installed BLE Scanner onto my phone (an iPhone). is all the same, I think? Anyways, so that keeps happening. Something not super interesting is still happening with mods for me, which is that when I calculate a tool path from mods while at the EECS shop, it seems to assume that the mill is larger than when I calculate a tool path from mods from my laptop, and I don't understand why this is happening? The mill diameter, min cut depth, etc. This LED turns on and does some blinky type stuff that indicates the board is working. I only added one LED (green with 499ohm resistor)(to P0/2 and not P2/0, which is I think what Rob did). I followed Rob Hart's tutorial to get everything set up. I basically remade Neil's board, but with an LED added to indicate that things were working. AKA I played around with RN4871 2.4GHz bluetooth module. This week, we made a thing that could talk to another thing.
