Excelent work Kevin. I have been strugling to make ble to work on MicroPython and this vídeo is the first one to put me in the right path . Thanks a lot.
Thats great to hear!
Thanks for the tutorial Kevin. I have been struggling to get BLE working on my Pico W for some time and this has helped a lot. I have a project where I want the peripheral to stop advertising for say 5min until the next piece of sensor data is available. The client should keep scanning. What is the best way to stop the peripheral from advertising until data is available to send? Cheers Tristan
Very interesting. I would like to use this for a battery powered temperature sensor connected to my central heating water supply pipe. It needs to log once every 10 to 15 minutes. However, can I use BLE and WiFi at the same time? How could I push my sensor readings to my InfluxDB over MQTT while still reading BLE data?
Hi Kevin enjoyed this. I'm a believer in distributed processing so inter board Comms is always of interest.
I have a suggestion. How about doing a bridge device based on a ESP32 Stamp sized board that would look like a UART on one side ESPNow or BLE on the other. That way just about any board could be linked even UNOs. I use PiPico but they don't support my favourite inter board communication ESPNow. Keep up the good work 👍
Can you make a Pico communicate with another throw there’s own WiFi, without the wifi in the house. Would be great if I can make a rc-car with controller that can drive outside.
I have a Pico that takes data from a DMM via uart... I'd love to have my PC communicate to the Pico wirelessly to see that data. I have a couple USB Bluetooth dongles for the PC ( Feasycom BP102, HC-05/HC-06/CP2102 master modules)
Any thoughts what would be involved in writing an Pico application, that takes the uart data and passes it wirelessly either via bluetooth** (SPP) or via Wifi?
For Wifi, I imagine the Pico could act as a web server (TCP) and display the RS232 data, but maybe there's also a UDP way of having the Pico send the data to a PC on the same network?
Can I have an ESP-32 talking to a pico w using this exemple ?
Yes I've tested this with an ESP32, I did have to install the aioble library for that to work (using Thonny's package manager in the Tools menu -> search for aioble and click install)
@@kevinmcaleer28 Thanks
Good job on this project. Which editor are you using if you don’t mind me asking?
You mean to edit the code or edit the video? For the Code I use Microsoft Visual Code (I used Thonny on the stream to show the code). For editing video - this was all done live; I use Ecamm Live to switch between cameras and scenes, Keynote for the presentation and a combination of Omnigraffle and Canva for graphic design. I edited this video with Final Cut Pro (macOS) as the live stream stopped after 8 minutes and I needed to stitch both parts together and reupload
@@kevinmcaleer28 thanks for sharing. I was wondering what editor you were using to show the code during the video.
Hi Kevin, I'm thinking about steering Lego trains with bluetooth. I don't want to use ESP-now that would be somehow closed technic, or MQTT via the WLAN. Would it be possible to setup a bluetooth Mesh or a bluetooth hub , could be work off grid?
... or ble
sorry, or better a ble hub (one to many relation)
Great question - how many separate trains would you look to control? Is the control via a single track controller (i.e. all the track controls is done via a single device). Bluetooth on microcontrollers is only device to device at this point, however one pico could control all the tracks paired with another pico that is the wireless remote; no mqtt or wifi required.
I tried the code and noticed that when I stop one of the picos the other continues to receive messages that it itself has sent, in a continuous loop. I thought it was some kind of bufferized messages on a queue being treated but it is not. When I restart the stopped pico all the communications restarts without problem
@@JeronimoAvelarFilho the other Pico will try and send messages while it can, but should stop ones the other disconnects.
@@kevinmcaleer28 I will verify and test again when I return home.
