BLE and BluetoothSerial not working together

Hi all, I am hoping this is an easy one. I am hoping to use BLE (for blufi, which I have got working nicely) to work at the same time as Bluetooth classic SPP. The goal is to be able to (re)configure wifi at any time while connected to an ELM327 over a bluetooth (to serial) connection. Unfortunately...

Re: esp_https_ota is complaining about "invalid size"

Thank chegewara, I saw your issue. I had looked over the issues before but never clicked on yours for whatever reason. The solution was to call esp_log_level_set("*", ESP_LOG_ERROR); Additionally, I had to disableCore0WDT(); because of how my code is set up. I think I'll move things around in order ...

Re: esp_https_ota is complaining about "invalid size"

Thanks! That seems to have helped. Now it hangs on writing for a few seconds then spits out: I (33763) esp_https_ota: Starting OTA...

esp_https_ota is complaining about "invalid size"

Hi all, I am trying to use esp_https_ota to update my app from an HTTPS server. I verified that my server implementation returns exactly the same response as the python "simpleHTTPServer" that is used in the official examples. I also verified that my TLS information is correct, and the connection su...

esp_crc16_be not available in 4.0, what can I use instead?

I am using platformio with IDF v4.0, and the appropriate arduino libraries as a component. I am hacking and slashing away at the Blufi demo, and have finally gotten my phone to communicate with the esp. I did, however have to do this: uint16_t blufi_crc_checksum(uint8_t iv8, uint8_t *data, int len) ...

Partition for large app with OTA support

Interrupts not firing at right time after switch from arduino framework to idf with arduino as component

Recently I decided it was time to switch from using only the arduino framework to using IDF with arduino as a component. In my code I have an interrupt that performs 3 distinct action, one after the other, at very precise times: void IRAM_ATTR ControlPilot::Pulse(void* arg){ TIMERG0.int_clr_timers.t...

Re: 100microsecond timer in esp32

static void timer_isr(void* arg) { TIMERG0.int_clr_timers.t0 = 1; TIMERG0.hw_timer[0].config.alarm_en = 1; // your code, runs in the interrupt } Just wondering why you re-enable the alarm. IIRC When you set TIMERG0.hw_timer[0].config.autoreload it should remain enabled even after the alarm is trigg...
