Re: RMT, 1-Wire Slave and timing woes in general

After a break and a bit of a rethink I finally got it working, though slightly puzzled why it didn't in previous tests. I didn't initially fully understand the relationship between rmt_conf.clk_div and tick rate and now I do, I was never sure on the correct values to set for rx_conf.filter_ticks_thr...

RMT, 1-Wire Slave and timing woes in general

I have a project that requires me to emulate a simple 1-Wire Slave device. HoHo, no problem pmckeon! I hear you say, just use https://github.com/orgua/OneWireHub Except it's part of an existing project I've mostly completed in the native Espressif IDF and that library was made to work with the Ardui...

Re: Clear the BLE whitelist

I'm not ready to give up on this yet :)

Surely there must be someone familiar with the BLE stack in the IDF?

ESP32 Development Board with 3.3v in and USB

I have an ESP32 Development Board (or at least a clone of one) that I was intending to power via a 3.7v lithium cell -> charge controller -> 3.3v voltage regulator on the 3.3v pin Is this going to upset or damage the existing 3.3v regulator onboard? What if I had both the USB and external 3.3v regul...

Re: Clear the BLE whitelist

Sorry to bump this again but it's been buried under the other threads and I'm keen to get some insight.

Re: Arduino ESP32

I can't comment on compiling Arduino core from Eclipse, but I was able to successfully install and compile from the Arduino IDE using these steps:

Re: Clear the BLE whitelist

Any chance of some insight on this from Espressif?
How is the whitelist managed if you can only add or remove but not view or delete (clear) the whitelist?

Re: Clear the BLE whitelist

As an example scenario, say I have whitelisted a device and have the filter policy set to ADV_FILTER_ALLOW_SCAN_ANY_CON_WLST allowing connection from only whitelisted devices then later want to remove the device from the whitelist without knowing what it's address was is there any way to simply clea...

Clear the BLE whitelist

I am trying to figure out how one can clear the whitelist if the old device address is unknown. esp_ble_gap_update_whitelist(bool add_remove, esp_bd_addr_tremote_bda) Will allow you to add/remove devices, but in the scenario you want to clear the whitelist and revoke any previously added devices the...
