Client approaches with the problem of frequent crashing of esp32. His client was not happy with the frequent crashing of esp32 and needed to fix the issue within a week. After looking deep into the problem, I found t the issue was memory was due to memory leak. Previous developer allocate the memory but forget to deallocate it after using it. Due to which there is no free heap available in the system, due to which code crashes and system restart. After looking into the code I figured out which function is allocating more memory and from that function I start host base heap tracing. I have JTag adapter with me. After including the host based debugging I generated the trace which gives me the function which are allocating and deallocating the variables. From that I find out the lines which are allocating the memory but not de allocating it. Fix the bugs.

I have to design the 2 apps. One for the peripheral and other for the central. The project requirement is to code using the esp-idf framework. Each apps have the separate file for each different functionality The peripheral device measures the temperature. After measurement device initialize the Bluetooth low energy. If ble have been initialized, then has to send the message to the central device in the JSON format. After sending the message, peripheral will be in deep sleep for specific time and the cycle repeats itself. Central device will have initialized the ble and wait for the peripheral to send the data. Central device will look for the ble device After authorising the peripheral device will print the json message on UART. After that will create the task to initialize the wifi and look for the wifi access point. After connecting to the wifi it will pubish the results to the mqtt server. After that I need to design the kconfig file also.

Ankit has done excellent work, and despite our specification not being very clear, Ankit understood what it was about and implemented it correctly. Change requests and new features were also incorporated promptly. We will definitely rehire Ankit when we have a suitable project.
