What is the recommended size of the BLE task stack? We use both peripheral and central role.

Hi,

I use a ESP32 WROVER and run IDF 4.4.3.
The device is setup as BLE central and peripheral.
If the device connects to a peripheral and the peripheral sends more than 150 bytes in a notification (frame will be fragmented)
the device crashes with this crashlog:

***ERROR*** A stack overflow in ...

Hi,

I'm using IDF version 4.4.2 and sometimes get task watchdog triggered when calling function nvs:_set_blob.
Task watchdog get triggered continuously and no hard reset is performed so the system is stalled.
On line 1351 In log log_221121.txt it is for the first time triggered.

What might be ...

I set wifi module in STA_AND_AP mode and try to connect my PC to it.
It seems like it connect and 60 ms later disconnect, with bss_flags 658531.
Does the bss_flags give indication to the reason why it diconnects?

Logs:

Hi,

I'm using a ESP32 as a TCP server. A PC is client and connects without any problems to the server. After a while (10-15 minutes) I get ECONNABORTED and I can see in Wireshark that ESP32 sends RST flag to client.

What might trigger this behavior?

I added a log with debug printouts enabled, seems like assertion fails in ble_gap.c line 1166:

Hi,

I use IDF version 4.3 and uses NIMBLE stack both for central and peripheral role. Sometimes the NIMBLE stack crashes when peripheral is connected and central is trying to connect to a device.

I've registered two different reasons for the NIMBLE stack reset:

0x0c (12) BLE_HS_ECONTROLLER Event ...

This is what the code is doing:

1) Advertising is started from on_sync() function and restarted at CONNECT and DISCONNECT event using

ble_gap_adv_start(own_addr_type, NULL, BLE_HS_FOREVER,&adv_params, test_gap_event, NULL);

2) Every 10th second a scanning to to fins peripherals is performed ...

I scan during 5 sec with an interval of 10 sec. Is that ok? I constantly advertise.

rc = ble_gap_disc(own_addr_type, 5000/*600*/, &disc_params, passive_scan_event, NULL);

When I restart advertising do I need to call these functions:

ble_gap_adv_stop
ble_gap_adv_start

Or do I only need to call ...

Hi,
is it possible to scan and advertise at the same time use the integrated BLE in ESP32? I use NIMBLE stack and version 4.3 of the ESP-IDF.
Can I start advertising and periodically scan for other devices without stopping advertising?

I added a Wireshark BLE sniffer log. The central can't connect ...
