Difference in behaviour for sending custom data in IOS and Android
abhisheksoni099 opened this issue · 3 comments
I found difference in behaviour on how Android and IOS application sends custom data to ESP32.
Below are my findings for IOS and Android data transfer:-

Data sent from an Android application and received at ESP32
1. Data is transferred in a single fragment for any data size
2. This is the expected behaviour

Data sent from an IOS and received at ESP32
1. Data is sent in multiple fragments rather than a single fragment(16 splits)
2. Each fragment contains a incorrect character at the beginning
3. Some initial characters are not getting transferred
Below are the logs from ESP32 while it receives the data from the IOS, transferred via Bluetooth

For IOS correct data is being sent only in the cases where there is only a single fragment being transferred(small data size)
Data being sent from IOS to ESP32
{"product_type":4,","product_ip":"192.168.1.202"}
1. It transferred correct data when single fragment is being transferred from an IOS
ESP32 logs transferred from an IOS below

My questions
1. How can we send data in IOS just like the way android does(in a single fragment)?
2. The multiple fragment transmission in IOS is sending incorrect data which may be corrected although I would request code changes to make transfer in a single fragment
Any update on this?
We have updated codes to fixed long custom data bug on iOS.
iOS can now send large custom data with the code changes. Thank You 🙂👍
