ESP32 - Multiple Advertisment Packets
Hello Everyone, Is it possible to support two advertisement packets with the ESP32 at the same time. Ideally, I'd like one advertisment packet to be used for configuration GATT server, and the other for a GATT Server which used the HID profile. I can see there is support for multiple profiles - but ...

Re: How add another Characteristic in the example 'gatt_server' (BLE-Bluedroid)
Hello Gustavo, I was working on this as well. I'd like to show you what I've learned if you're still struggling with this. When the service is created, the following event is triggered in the gatts_profile_event_handler case ESP_GATTS_CREAT_ATTR_TAB_EVT:{ ESP_LOGI(GATTS_TABLE_TAG, "The number handle...

ESP32 - GPIO39 Glitch with BLE Modem Sleep
Hello Everyone, I saw in the chinese forum someone report the same issue. There is an issue where the ESP32 will pull-down GPIO39 when modem sleep is enabled. This is not directly noted in the Errata. I suggest the team update the errata to show this. I'm also wondering if there is anyways to preven...

Re: ESP32 - JTAG Non-Functional w/ Stock Firmware
Thanks @krzychb for the quick reply.
I found another post which the author said he could erase the firmware via JTAG, and then program.

ESP32 - JTAG Non-Functional w/ Stock Firmware
Hello Everyone, I purchased 4 raw ESP32-WROOM-32 modules from Digi-key, soldered them to my hardware, and then attempt to flash them over the JTAG interface. Every attempt of programming the module left me with the dreaded all ones seen blah blah blah error. All of the existing documentation online ...

Re: ESP32 Cosine Generator to SPI via DMA
I did a few experiments and Nyquist seems to be fine based on the outputs of the FFTs post the output of the receiver. Thanks!

Re: ESP32 Cosine Generator to SPI via DMA
Gotcha. Hmm. This means that you almost need a 'streaming' mode for a SPI transaction, like the I2S peripheral has. At the moment, the driver has nothing of that kind, but the hardware supports it; worst case you could hack the driver to get something like this. Okay cool! I'm guessing the I2S driv...
