Gazell data lag when more than 1 device is connected

[LT_Viktor]

Hi! I am fairly new to programming micro controllers so apologies if I ask many questions. I am using NRF52832. The situation is this - I have 2 devices and 1 host . After receiving data the host then sends data via UART to FT232RL and then to a computer. The devices are running on different pipes, however when both devices are sending data to the host some bytes are being skipped and there is this lagging as well - the data comes not consistently but in steps. Any ideas or advice ?

Here is the host's main code Host Device.txt

And here is the devices' code (it's quite a mess, sorry). Device.txt

Ok. I have managed to fix the byte skipping by using this answer. However, now I have data coming in little bursts at first and then it slows down gradually to a very slow rate... When I reset the host same thing happens again.

Hi Viktor

Are you still experiencing issues with packets arriving in bursts?
One thing you can try is to set a shorter timeslot on the device side than on the host side (try values 20-50us shorter). Then there is less chance that the device will drop completely out of sync, and have to retransmit the data several times to get back in sync (if the device is faster than the host you typically get away with a single retransmit to get back in sync).

Best regards
