I want to connect a bluetooth module to communicate with the controller via a mobile application, but I don’t know how to do it correctly. I have no practical experience, can you explain the algorithm of work to me?
The nRF52832 module according to the manufacturer's firmware with uart support is preinstalled
I connected pins rx---tx, tx---rx, vcc---+3.3, gnd---gnd.
but it is not activated when the controller is started, what actions are necessary for it to work?
I have a problem that I can't run the module, it is not recognized in the bluetooth
the controller connects via usb to the computer without problems and vesc tools
This is the sheer module. You need additional components surround it. A 100uF and a small 2.2uF capacitor at least. These modules are made to be soldered onto a PCB holding the additional components.
The module also needs the correct firmware loaded via SWD.
the one with a larger capacity should be installed in parallel with the power supply, the one with a low capacity in parallel with the signal one?
the firmware is the one from the github on nrf52, yes?
The caps need to be installed on the power supply lines and the smaller cap really close to the pins. You need to look deeper into the data sheet. Best thing you can do is purchase a module that already sits on a carrier PCB or this one with the firmware pre-installed: https://trampaboards.com/vesc-connect-nrf-wireless-dongle-with-external-...
Where are those Px.y (TX) and Px2.y2 (RX) pins on the nRF52832 module mentioned here https://github.com/vedderb/nrf52_vesc ?
