Realtek IOT AmebaD 6.2 SDK Release Note
We recommand the flow items:
1, Apply the lastest Patch will make your project synchronize with our Git branch code, and will make it easier to analysis some issues or implement requirements
2, Try not to modify the .c and .h files in default SDK. If you are obliged to do this, add your own marco between your code, and it will make it easier for you to merge Patch
a) If the .c and .h files in Patch are not modified in your project, just copy and paste
b) If the .c and .h files in Patch are modified in your project, use compare tool to only merge the difference which are not changed by yourself

Symptom: Within mesh example, when wifi is connected, there is sometimes pb adv link open fail or link busy problem.
Reason: When wifi is connected, coex tdma mechanism is working, making a 100ms TBTT to separated wifi and bt slot. So there is a possibility the pb adv connect ack sending from responser will locate in the wifi slot, making the pbadv con procedure time out.
15, Optimize BLE Log
Symptom: The log of BLE read & write is shown unclear.
Reason: The format of BLE read & write log should be optimized.

Git 210407_733408e9 to Git 210413_fe817a24:
1, Fix WIFI Bug
Symptom: Timer Task may block when sta leaving in softAP mode
Reason: Timer queue length is only 10, station leaving will cause del timer event more than 10, so need to increase timer queue length
Git 210413_fe817a24 to Git 210428_13a21db4:
1, Improve the compensation of thermal effect on BLE TX power

5, Support Read large websocket data when the fin field is not set in first packet
6, Disable PMF function in SoftAP mode
7, Add wifi simple connect API
8, Support IAR debug reset when wifi is running
9, Update HTTP related code
10, Fix BadAlloc vulnerabilities in FreeRTOS
11, Fix rx packet miss bug when packet is special length from special AP
12, Update Audio related code
13, Fix BLE Bug
Symptom: Change the delete order of task and message queue when BT deinit.
Reason: Delete message queue first may cause hardfault in some cases.
14, Fix BLE Bug
Symptom: Disconnect two BLE links at the same time may cause error.
Reason: Controller do not support disconnect two BLE links at the same time.
15, Optimize BLE Mesh
Reason: Update BLE Mesh SDK to support Mesh 1.1.
16, Fix Security Vulnerabilities in Fragment and Aggregation attack
