I would like to make a mesh network with bluetooth 4.0 BLE modules.
Which modules supports the mesh topology (eg.: HM-10, HM-11 or something else) ?
Thanks
@torfinn These settings should make it work, regardless of which version you buy:
// If you are using an RF-Nano, you have to switch CE and CS pins.
#define MY_RF24_CS_PIN 9 // Used by the MySensors library.
#define MY_RF24_CE_PIN 10 // Used by the MySensors library.
// Enable and select radio type attached
#define MY_RADIO_RF24
#define MY_RF24_PA_LEVEL RF24_PA_MAX
// Mysensors advanced settings
#define MY_RF24_DATARATE RF24_1MBPS // This datarate is supported by pretty much all NRF24 radios, including the RF-Nano.
@mfalkvidd I tested shorts with my multimeter and didn't find any shorts. However I should receive next week some new of these chips and I will try to solder them new. Let's hope that that's the issue!
A datasheet for the new nRF5340 is now available: https://infocenter.nordicsemi.com/pdf/nRF5340_OPS_v0.5.1.pdf
It has some improvements, but some of its competition seems to be much lower power.
It's not a perfect pin-out match. You should definitely check out this thread:

But you're right, it's great for beginners. That's why it forms the basis of the Candle project.
@sundberg84 Yes, but I wonder if it will also work if I use the regular (round) THT pads from the Pro Mini (as the cheapest and most widely found Pro Minis seem to be like these)
I'll probably just try it I guess, but of course have to adapt my PCB accordingly to get the castellated half holes. Hope my PCB manufacturer knows what to do with the KiCAD file.

Hello
Before my post was approved last night I did realise I was missing capacitors on the rf24 modules. The node has the rf24 module powered from the 3.3v pin of the arduino mega. The raspberry pi gpio 3.3v is powering the other rf24. I have ordered some capacitors so will see if that helps when they arrive sometime next week.
Thanks for the help
