Re: SPP with Legacy Paring and STATIC pin code

Boom. Right on the money. Ok, glad i'm not going crazy and this is a good question to be asked. Thanks for the find. So, at the moment, we know we cant do what im asking for. That its going to default to SSP if the non esp devices supports it. Hopefully we have a function to turn off SSP for these s...

Re: SPP with Legacy Paring and STATIC pin code

Try this https://github.com/espressif/esp-idf/blob/fac12d0daeb0c69dc60d6f60bc6341f074908e61/examples/bluetooth/a2dp_sink/main/main.c#L117-L132 only change i think you need to do is ESP_BT_IO_CAP_IO -> ESP_BT_IO_CAP_OUT. Tried that. It puts it in the "just works" categories for most android phones I...

Re: SPP with Legacy Paring and STATIC pin code

More notes: For classic, in setting security parameters: esp_bt_sp_param_t param_type = ESP_BT_SP_IOCAP_MODE; esp_bt_io_cap_t iocap = ESP_BT_IO_CAP_IO; esp_bt_gap_set_security_param(param_type, &iocap, sizeof(uint8_t)); and its enums: typedef enum { ESP_BT_SP_IOCAP_MODE = 0, /*!< Set IO mode */ //ES...

SPP with Legacy Paring and STATIC pin code

I'm having a hard time coming up with a solution to this desired use case: - BT Classic - Legacy Pairing (NOT SSP) - ESP has a static PIN for bt connections - Phone scans and wishes to connect, provides with a static PIN when pairing - ESP verifies PIN and pair occurs - Then can proceed with SSP int...

WiFi scanning procedure without AP to connect to

WiFi Scan is now an issue if you ONLY want to do a WiFi scan. Lets say i want this following scenario: - Boot - Configure wifi driver - SCAN FOR ACCESS POINTS WITHIN AREA (IE : There is NO access point to connect to, or want to connect to!) We used to be able to do this. But with the new updates to ...

Re: Esp-mdf - cross platform mesh with esp32 and esp8266

Looks like the new website makes it more clear about the number of devices:

Re: ESP-MESH: Each node needs knowledge of the router ...

That's what i was thinking... if we were forced to have an AP, i would just write some code to designate an ESP as an access point if needed. I haven't had time to mess with mesh yet, but its on the chopping block. I was hoping giving some more time might give some more clarity as they work out some...

Re: Using protected efuse keys for AES? (But not encrypted flash)

From my understanding: Looks like they left it to be used for the public key for remote signing for secure boot:

also suspicious that its just the right size for a key.

Re: Simple MQTT with C++ and IDF

Thank you all for your help. After trying out all solutions, i did make some progress with the ones posted. Ended up that the project if written in C++ was getting to be too large in code size to be able to handle a factory/OTA_1/OTA_2 since we're doing BLE/WiFi/OTA/MQTT and some other peripherals. ...

Re: MQTT_TX_BUFFER_TOO_SHORT_ERROR on AWS IoT embedded C

I know this message is a bit old now, but i was running into the same issue today. Solution is, you dont just change it in the .h file, as that will be overwritten by the values in "make menuconfig" so: make menuconfig -> component config -> amazon web services .. -> MQTT Tx Buffer length (512) Chan...
