Read or set retransmission count in BLE

[mbiglari]

Hello. I'm using esp32-S3 with IDF with Bluedroid stack for BLE. I need to calculate the packet reception ratio between two BLE devices. So I have created a central and a peripheral device to communicate with each other. Then I gave a fixed channel map to enforce BLE to use just one channel for communication. Then I changed my WiFi channel to the same frequency as BLE to create noise on BLE channels. Although Wifi and BLE had interference with each other, I received packets completely. I think BLE does retransmission on the link layer. Therefore, can I find the number of packet retransmissions or can I set this value to calculate the packet reception ratio in a noisy environment?

Thanks in advance for your help.

How did you determine that there was 'interference'? What kind of interference?

Dear MicroController

I want to calculate the packet reception ratio. So I fixed my wifi channel to channel one and my BLE channel to channel four. these two channels have the same frequency. So when I started to transmit data with BLE, Wi-Fi interfered with it, and some of my packets must be dropped but because of retransmission in the BLE link layer, I received all of my packets completely. Hence, I need to disable channel retransmission or count the number of retransmissions to calculate PRR.

Because of the WiFi/BLE coexistence, I doubt this assumption is correct.
