Re: [VIDEO] Freshen - device management for ESP32

Hi can't compile the library (freshen.h) with the latest esp-idf...

Re: No esp_ble_gap_config_scan_rsp_data() ?

Hi

thanks for your response.
How can I pass the two structs to the driver? I have to call the function esp_ble_gap_config_adv_data(&adv_data) twice?

No esp_ble_gap_config_scan_rsp_data() ?

Hi from what I could find, it seems that a function to set the scan response data is missing in the framework. We do have the corresponding event: ESP_GAP_BLE_SCAN_RSP_DATA_SET_COMPLETE_EVT and we also have a member (set_scan_rsp) in the esp_ble_adv_data_t struct that it seems to suggest that you ca...

Re: ADC calibration with VREF

Hi thanks for your reply... I was able indeed to use the read value in: esp_adc_cal_get_characteristics(V_REF, ADC_ATTEN_DB_11, ADC_WIDTH_BIT_12, &characteristics); but this method assumes you measure the voltage for each board you program and adapt the code accordingly... I was looking for a "softw...

ADC calibration with VREF

Hi all I'm trying to follow the instruction on the official documentation to calibrate the ADC: https://esp-idf.readthedocs.io/en/latest/api-reference/peripherals/adc.html I was able to route the internal VREF to GPIO25 and read the value with a multimeter, it's 1.146V: ESP_ERROR_CHECK(adc2_vref_to_...

Re: How can scan particular BLE devices?

Hi

don't know what a "pbeacon" is, but if you meant iBeacon, the framework does include an example about how to scan for those devices:

maybe you can change it to search for "pbeacon" specific advertising data...

Re: Unable to use the "official" SPIFFS wrapper

Hi loboris, first of all thanks a lot for your work: with your code I was able to complete my project! It sounds strange to me that Espressif included a SPIFFS wrapper in its IDF 3.0 but at the moment there's no mkspiffs compatible... for Espressif guys: my suggestion is to include also the mkspiffs...

Re: Unable to use the "official" SPIFFS wrapper

Hi during the weekend I reworked the program to use the spiffs hal from loboris and everything works fine... I had to use its version of mkspiffs too... this evening I'll post the modified program... so it seems the official wrapper doesn't work for me, anyone was able to use it successfully? thanks!
