BLE communication between ESP32 & NRF5340

[Mr.NCK]

Hi, 

 I am now working on communication part between esp32 and nrf5340. I want to send the data via ble from nrf5340 and it will receive by esp32. Now, I can able to connect both the devices by giving proper service uuid. But, to read the data which is send by nrf5340. I need give characteristic uuid. I have tried with the Tx characteristic uuid which was shown in nrf connect mobile application. Even, I can't able to connect to read data. So, kindly tell me how can i resolve this.

Thanks & Regards

I would recommend you to watch the webinar Developing Bluetooth Low Energy products using nRF Connect SDK, which goes through how to set up a BLE project in NCS and how to set up your own characteristics.

Hi Simon,

I have gone through the video, For BLE UART, I can use the default characteristic UUID right. I can't able to connect with the default characteristic UUID to receive data from nordic to esp32.

Thanks & Regards

Could you upload some relevant code and explain your issue in more details?

[Mr.NCK]

Hi simon,

  Now, i have tried with  some other way, i need to know one thing what is the minimum input current for nrf5340?

Thanks & regards

Could you open a new ticket about the nrf5340 current consumption? Since it is not related to the initial question (BLE communication).

Okay simon,

 I need to transfer data from nrf5340 to esp32. Then from esp32 to cloud by using wifi. This is what we are trying to do.

I have tried lots of way. But I can't able to crack it. I can able to create connection among them. But the data will not received by esp32. In nordic i am using ble peripheral sample.

Kindly, guide me in a good way to achieve this.

Can you upoad your modified ble peripheral sample and I will take a look at it.

Best regards,

Simon
