Re: [JTAG] [openocd] Error: DIR instruction generated an overrun!

Thanks, it works ! I went into the both cfg files (esp-wroom-32.cfg & jlink.cfg) and wrote adapter_khz 10000 . The problem is that openocd used to say that 20000khz is to much and change it to 15000khz. But 15000khz is still too much so it gives an error but that error do not mention any speed issue...

Re: [JTAG] [openocd] Error: JTAG scan chain interrogation failed: all ones

Just found an explanation.
Somehow, the ft2223h forces some pin to 2.5v and so those pin are considered as "high", that's why I got the "all one" error. This 2.5v level is constant and can't be changed so no information can be exchanged.

So I guess my ft2232h jtag interface is broken.

Re: Security problem in pairing mode (AT+BLEENC)

I opened the samed issue on the git and had a quick response: we can't set a pairing key for the moment. The feature may be added in the future

Re: Security problem in pairing mode (AT+BLEENC)

Thank you, it works ! I didn't think that it would need an AT security configuration plus a service.bin perm configuration.

I still have an problem, but different: Is it possible to set a static pairing key ?
For the moment, the pairing key is set automaticly with "+BLESECNTFYKEY:0,xxxxxx".

Re: [AT command] Add "at_customize.bin" and "service bin" directly from the ESP32

Hi, in fact there are differents firmware "levels". I resolved my problem so here is a little explenation: 1. When you buy an esp there is the basic firmware with basic AT commands. 2. If you want Bluetooth Low Energy AT commands, we must flash the firmware, you can check this tutorial . 3. If you w...

Security problem in pairing mode (AT+BLEENC)

Hi, AT+BLEENC seems to work only if a device is connected, wich is concerning because the client can write/read during a short period of time without any permission. For the context, here is a git issue tackling the problem but without solution: https://github.com/espressif/esp32-at/issues/45 Did I ...
