Re: Debugging blecent application on nrf52dk

Yes, that is for 4.2. But earlier versions of the specification do not even mention Data Length Update procedure so this would not apply to a 4.1 controller, for instance. There needs to be a generic place in the spec that says “if you receive a LL control opcode that you do not understand,

Re: Debugging blecent application on nrf52dk

Hi Will, Thanks for the explanation. I found it in the BluetoothCore v4.2 spec in section 5.1.9 - Data Length Update Procedure. I agree with your conclusion that it sounds like the controller must accept LL_UNKNOWN_RSP but must not require it. Thanks again this was really very helpful. -Pritish

Re: Debugging blecent application on nrf52dk

I can elaborate. It has been discussed at fair length on the dev list before but I will summarize. The issue is that our controller automatically attempts to do data length extension with a peer. The default configuration sets a larger receive size than the minimum size and this causes the

Re: Debugging blecent application on nrf52dk

Hey Will, That worked!! The blecent is staying connected to the bleprph almost indefinitely now. Can you please elaborate on the reason: "And sure enough, I think this is the same issue we have seen before. The data length update procedure is not completing and the connection is timing out." Do

Re: Debugging blecent application on nrf52dk

BTW: Lukasz did have a really good suggestion for future debugging (why didnt I think of that?) :-) A sniffer with wireshark is a really handy tool. I mentioned the debugger as it was something we could look at really quickly to see if it is an issue that I already know about with some

Re: Debugging blecent application on nrf52dk

Hi Will, Sorry I was mistaken, I jumbled up the issues in my own head. You are correct in that the blecent is running on the nrf52dk and the logs I provided are from the blecent application. As you requested I put the breakpoint at ble_ll_ctrl_proc_rsp_timer_cb() please see the dump below:

Re: Problem to use newtmgr through ble

Dear Chris, When i put sudo newtmgr -c BT01 stat list, it gave me sudo: newtmgr: command not found. Dear Andrzej, I get the following error with you suggestion. $ sudo setcap cap_net_admin=+ep 'which newtmgr' [sudo] password for dev: Failed to set capabilities on file `which newtmgr'
