Re: Bricked? ESP-WROOM-32D stuck in boot loop after running unit tests in PIO

Hello ESP_Sprite, thank you very much for your reply! :) I tried the command you suggested (i guess it's the same that ive tried from within platform io). Unfortunately the result is (almost) the same. I actually de-soldered the esp32 module from my pcb and replaced it, and my board is now working f...

Bricked? ESP-WROOM-32D stuck in boot loop after running unit tests in PIO

Hello, After developing a custom hw baord using the ESP-WROOM-32D module in VScode (using arduino) for a couple of weeks as a part of a student exam project, i was going to run some unit tests using platformIO. After creating a simple test in the testfolder and uploading it and running it the termin...

Re: TWAI/CAN am I using the functions correctly?

Hi again, if anyone else has this issue my problem seemed to be related to faulty SN65HVD230 transceivers that did not ACK the frames. I changed my setup to a MCP2515 transceiver and a logic level shifter and the above code worked. So if you are having issues, maybe it's the transceiver, i bought mi...

Re: TWAI/CAN am I using the functions correctly?

Ok, so by the number of answers here, im guessing that there is not that many people that uses twai/can.. :D Anyway, i hooked up a picoscope to look at the canbus, and i could see that the esp32/transeiver never acknowledge the message (sets the ack field to zero). Im not sure if the ACK is somethin...

Re: Is possible to break down the current consumption keeping the BLE connection?

I have zero experience with sleep modes and current consumption, but it sounds to me like the best scenario for you is to wake up periodically to take your measurement and then only enable BLE if you have anything to "new" to transmit. Also if timing of event is not a factor, maybe you can store the...

TWAI/CAN am I using the functions correctly?

Hello! I've been trying to communicate with a VESC motor controller using the TWAI on the ESP32 for a while now, i've based some code on the examples and picked what i thought was neccesary. Im able to add the config and filter (ACCEPT_ALL), install and start the driver without any errors. Then i ju...
