Re: LWIP/sockets memory leak?

Is it still there if you don't stop/start wifi? Although 3.1.1 includes https://github.com/espressif/esp32-wifi ... 32f332c4e7 so maybe not.

Re: High Level Interrupt on external GPIO Interrupt

Are you sure ESP_INTR_FLAG_HIGH returns a level 5 interrupt since it matches more than one level?

Re: running ESP32-D2WD at 240 MHz ??

You can put small programs wholly into iram, most people are using too big of a program to do that. pico D4 comes with passives and the crystal inside, which you would have to fit in that 24mm² including trace routing to come out even. It is possible the reason for the 160mhz limitation is thermal c...

He meant did you also set ESP_INTR_FLAG_IRAM

Re: MTDO Strapping for UART 0

There are 2 bootloaders, strapping pin controls 1st, menuconfig controls 2nd. Internal pull is 30-40k I believe.

Re: SSL Certificate Renewal

Does your browser download a new certificate every 90 days? No, because the browser trusts the root certificate which has a longer expiration. However it can still expire so you have to be prepared to update it and recover from a device being offline for an extended time during which the cert expire...

Re: I2C device poses a challenge

20000 = 250 microseconds, max timeout would be 0xFFFFF = 13ms. However in no hold mode the device should be just nacking so you shouldn't be depending on that for your loop delay, use an actual delay.

Re: I2C device poses a challenge

You are still using E3 instead of F3. A conversion can take up to 85ms, would your loop cover that amount of time?
