BLE Mesh Relay Mode

Hello, I am using an ESP32 in a ble mesh network where sometimes messages have to be relayed. However, nodes only wake up once per minute (unsynchronized), so I want to "blast" the message (i.e. resend it many times) for a whole minute to ensure that someone hears it. How do I access the relayed mes...

Ultra Low Power Consumption for BLE Sensor

Hello, I am working on a BLE mesh sensor node running on an ESP32, and I need the power consumption to be as low as possible. My current implementation wakes up from light sleep once every minute and takes a reading. In some special cases, I want to send that reading through the network to eventuall...

Re: Torque of stepper motors

Hi, I am not familiar with that specific setup, but I built a 3d printer some time ago which I now use regularly (it is cartesian not coreXY). I used similar nema17 stepper motors for the x and y axes. I would recommend that you double up the motors on each axis whenever possible and/or consider a c...

Re: idf.py not found

I am working on a mac so I cannot vouch for the windows extension. If you cannot even install it, then I do not know how to help you. If you find a way to get esp idf on your computer, you will need to update your .profile to include something like this: alias get_idf='. $HOME/esp/esp-idf/export.sh'...

Re: idf.py not found

I have a similar setup. I use VSCode with esp-idf extension to write the code, but I always use terminal window to build flash etc. This seems to work well. I would suggest trying that first to verify that there is nothing major wrong with your setup.

Re: Issue with ESP-IDF "No ESP-IDF frameworks found"

Hello,
It might be a problem with the IDF_PATH environment variable. Did you set that to point to the esp-idf directory on your device? Check this out: https://docs.espressif.com/projects/esp ... ofile.html

Re: Can't compile BLE

I think the problem is with the state of BLE_42_FEATURE_SUPPORT in the header file. You can try to override it by removing the if/endif in the header file and forcing it to define esp_ble_scan_params_t no matter what. Remember to change it back later though.

Persistent Storage of BLE Config

Hello, I am working on a BLE connected device built on ESP32 WROOM 32D that may frequently lose power, but will be out of range of a provisioner when it wakes up. Because of this, I need the device to store its configuration in flash memory after it is provisioned for the first time and be able to t...

Re: Can't compile BLE

Can you post your whole CMakeLists.txt file? That might help me understand whats going on.

Reducing Power Consumption of BLE Mesh Sensor

Hey guys, I'm working on a sensor node on ESP32-WROOM32D that sends information periodically through a ble mesh network to reach one main node. One of my main constraints is power consumption/availability, so I have a piece of code that only sends the sensor status if there is a sudden change detect...
