Code help to receive data from zigbee receiver to ESP32 module and send to smartphones

Looking for some code help to send ZigBee temperature sensor data to ESP32 BLE module, I am thinking to connect the Zigbee receiver to ESP32 module and but to send data to BLE need some useful advice, any leads for these kinds of the solution will be helpful.

Derby I would point out that we have a category "Embedded systems" which is far more applicable to this sort of question than the "General" category, and is more likely to lead to your question receiving attention from those with expertise in this field.

Hello David Apologies for category selection, I am not able to change it now can you please help me out in this? I am the newcomer to this forum 

Derby, you can't change it after you posted.  Just copy and paste the question into a new question in the correct category, and if you can, delete the old one (click three dots at top right).

Hi there -- Max here (Editor of EEWeb.com) I just changed the category for you -- my bill is in the post LOL

Derby,Looking at the temperature sensor you linked,it's not actually Zigbee, but instead a 900MHz radio with proprietary "DigiMesh" protocol. If that's the sensor you're set on using, you'll definitely need Digi hardware at the receiving end and just talk to it from the ESP over a UART as Mike suggests. You also mention BLE, which doesn't really come into play at all in the above scenario. However, IF your application can be handled with the much shorter RF range of BLE, you can find a BLE temperature sensor that would potentially communicate directly with the ESP-32. Then a pure software solution could work. I'm personally not familiar with the BLE software stack on the ESP, but there must be a way :-)Cheers,- David

Hello, Shouldn't it be any other way than using TI CC2650 board, I am using the digimesh modem which would it be possible to connect with ESP32 and create the serial connection between them.  

Derby,So, it sounds to me like the problem is really to get the sensor data from the digimesh modem and send it to BLE.Unfortunately, I don't know enough about digimesh or ESP32 to give an exact answer but I can give some general guidelines.There are two parts to this problem.
First is to read the sensor data through the digimesh modem. I'll assume that you have the modem wired to a serial port on the ESP32. You should be able to find example code or library for ESP32 that communicates with a serial port. You will need functions to send and receive data over serial. It's likely that there are commands in the modem to allow you to read the sensor. So you send the commands and receive the data and store it somewhere.
The next part is to send data stored in the ESP32 to the BLE. There should be example code or library to do this. You may need to format the sensor data to meet the requirements of BLE and the app that will receive the data.This is a bit vague, I know, but I hope it helps.

The embedded processor chip has the freedom to determine the data route , handle graphics and animation requirements and almost the entire functionalities of the device in which it is embedded.
