Re: ESP32 PICO Custom PCB design

Thanks for the replies. I would like to know whether we can program it using an Arduino UNO or something? Do I have to buy a programmer separately just for this?

Re: ESP32 PICO Custom PCB design

Hello, Thanks for sharing the programmer board. I want to know what connections do I have to make changes in my schematics in order to program my MCU. https://photos.app.goo.gl/NV5BbWwbGKn7n6GSA Is it enough that I can just attach some header pins and program my MCU or do I have to do any additional...

Re: ESP32 PICO Custom PCB design

@Wifive, Thank you very much. I would like you whether I can programme ESP32 PICO without using USB connector. Which means apparently I am trying to cut out the CP2102 IC along with the USB connector. Are there any ways where I can programme the chip using Flash pins(I meant Flash_SD0, Flash_SD1, .....

Re: Multiple Client data handling with ESP32 BLE server

Hello, Thanks for the info. I am facing a problem in reading the data from the server on the ESP32 client. The data from the phone to server is beign sent properly, but the client is not receiving it correctly. The client side code remained the same as I shared in the previous thread of this post. A...

Re: Multiple Client data handling with ESP32 BLE server

I've made the following changes to the code that you've given to me. class MyCallbacks: public BLECharacteristicCallbacks { void onWrite(BLECharacteristic *pCharacteristic) { std::string rxValue = pCharacteristic->getValue(); //Serial.println(rxValue[0]); if (rxValue.length() > 0) { Serial.println("...

Re: Multiple Client data handling with ESP32 BLE server

Hey Bonadio. Yes, I am able to connect both my application and client esp32 to the server and successfully read the data. It is being updated simultaneously without any problems. Now, I am trying to send data from my mobile phone which is connected to server ESP32. This data must be sent to the clie...

Re: Multiple Client data handling with ESP32 BLE server

Hey Bonadio, Thanks for the reply. As you said at the intial stages of my work I have debugged everything using nRF Connect App. I do things in a very modularizing way. So, I've tested the things carefully and now I'm in this stage of handling multiple clients with ESP32 as server. Please suggest me...

Multiple Client data handling with ESP32 BLE server

Hello team, I've been working on an application where I need to make one ESP32 as server and it must connect to 2 clients. One of those clients is my mobile phone and another client is my ESP32. So, my goal is to send the data strings from mobile phone to client ESP32 via the server. How can I do th...
