Hello!
We are doing transfer from an Android app to a device using nRF52. We don't get the transfer speed I have seen other achieve. I get between 8.5-10 kbps. As a reference, if I run DFU I get 16 kbps. But I still want these ~100 kbps I have seen people talk about. We use SD132.
One of the comments on the high speed reached is for instance in this post. Also in the documentation there are higher speeds. Though that is higher connection interval than what is used.
The connection interval is set to 7.5 ms. nRF Connect reports 15 - 200 ms, whatever that means. (the interval I mean). We use "transfer without response". MTU size is 23.
I have gotten tips on "disable advertising". Isn't advertising automatically turned off when a connection is established? Is advertising a known "link hog"? I have tried, but not seen any real difference.
I apologize for these open ended questions, but I have no better way to try to explain this.
[Updated with reference to comments about transfer speed].
Thanks and best regards, /Stefan
