ESP32-P4 Waveshare Module

daviboi · January 24, 2026, 3:12pm

Hello everyone.

I recently got a ESP32-P4-Module from Waveshare but have been running into some issues with the WiFi and now, rebooting. Here is the module that I am using.

I found some similar topics that provided guidance with the WiFi configuration and the

esp32_hosted

Originally, the WiFi scan would find my network, but it wouldn’t connect. Subsequent scans after that did not find any networks.

Now, the watchdog gets triggered and the whole ESP reboots. Below are the logs and the configuration. Any help would be greatly appreciated!

It appears to relate to either cpu frequency or PSRAM frequency as it is replicable with limited config. I tried adjusting both but with no luck. I can replicate with the cutdown YAML provided here. The full YAML I use is here: https://github.com/chrisdunnname/esphome-p4-86-panel-eth-2ro-lvgl/blob/main/esp32-p4-86-panel.yaml

Looks like a wifi issue - add fast_connect to your wifi config. Problem goes away.

Issue and fix raise: [wifi] Fix watchdog timeout on P4 WiFi scan by clydebarrow · Pull Request #13520 · esphome/esphome · GitHub

  reboot_timeout: 0s
  fast_connect: true

daviboi · January 26, 2026, 1:32pm

I had tried both but I will confirm when I get back to the device. I completely missed this problem correlating with updating ESPHome.

daviboi · January 26, 2026, 1:33pm

This looks promising, I will give it a try! Thanks for finding that, I never came across that with my searching.

daviboi · January 26, 2026, 1:33pm

Yes, the P4 is using the C6 for WiFi since the P4 does not have native WiFi.

IOT7712 · January 26, 2026, 1:46pm

In this scenario, which chip does the ESPHome compile parameters address? One, the other, or both? Which chip is the ESPHome log reporting on?

clydebarrow · January 26, 2026, 6:58pm

You also need to turn off roaming:

wifi:
  ssid: !secret wifi_ssid
  password: !secret wifi_password
  power_save_mode: NONE
  reboot_timeout: 0s
  fast_connect: true
  post_connect_roaming: false

It’s fixed in the latest release anyway

clydebarrow · January 26, 2026, 6:58pm

The P4. The C6 has its own firmware that is not ESPHome.

daviboi · January 26, 2026, 8:38pm

Really appreciate your work on this Clyde!

daviboi · January 27, 2026, 12:30am

Hmmm I added both fast_connect: True post_connect_roaming: False
but I still have the same issue. The P4 picks up the network the first scan, then doesn’t the subsequent tries. Any guidance on how I screwed this up?

Just update to the latest version - 2026.1.2 - then you don’t need those. Though I always use fast_connect anyway, who wants a slow connect?

daviboi · January 27, 2026, 1:01am

I did update to 1.2 before flashing this time and completely agree, I usually leave that in for all of mine. I had to double check these logs to make sure it was 1.2 and didn’t flash an older build. Any suggestions i can pursue?

clydebarrow · January 27, 2026, 3:20am

I’ve flashed a P4 and will wait to see if it has any issues.

clydebarrow · January 27, 2026, 4:03am

It seems fine, but it’s not trying to roam.

Sounds good. Thank you for the replies. I’ll investigate further as it seems like it may be a hardware problem for me.

I have the Waveshare 86 panel, which is the same P4+C6 combination as the OP’s board but has a screen. Thought I would brain dump somethings I was looking at tonight.

Product:

Versions:
ESPHome version is: 2026.1.2

Slave C6 firmware was manually compiled with IDF 5.5.2 and updated from the P4 with the host_performs_slave_ota example from ESP-IDF. The master’s firmware was also compiled with the same IDF version.

I (2438) host_performs_slave_ota: Host firmware version: 2.11.5
I (2438) host_performs_slave_ota: Slave firmware version: 2.11.3
I (2440) host_performs_slave_ota: Versions compatible - OTA not required

I am seeing these errors and the wifi would only intermittently connect once in a blue moon. That too only after freshly flashing firmware from ESPHome.

Troubleshooting steps:

Used different USB C-C, A-C cables of various lengths
Used different AC power adapters, computers, power banks, power strips to power the device. All capable of providing >60W on type C.
Tested above combinations with both Type C ports on the device (UART and OTG ports)
Disabled WiFi fast_connect and the device will not connect, even intermittently.
Pinned this device in my WiFi mesh AP settings to one node, disabled roaming and force to connect to 2.4GHz (TP-Link Deco)

From the circuit diagram (PDF) of the board (relevant sections below), it seems like ESP_LDO_VO1 is tied directly to the ESP_3V3 net. On the ESP32-C6-MINI Schematic, the C6 (U1) receives its power at Pin 3 (3V3). This pin is also connected to the ESP_3V3 net.

So to me it looks like setting the LDO channel #3 on the P4 should not work to boost voltage for the C6 to the required voltage for the C6 to function as channel #3 is used for the MIPI screen.

From the docs, it seems like we can not control channel1 LDO either.

My preliminary testing seems to be a bit contradictory to the above as setting the voltage to the max 2.7V allowable level seems to have helped the connectivity a bit. I still get scan timeouts when first booting up but the device now at least connects reliably to wifi.

daviboi · January 29, 2026, 6:27pm

It looks like my original issue was hardware. I soldered a new module to a new board and I am now communicating with no problems.

Something I notice, it didn’t matter if I had the LDO config or not, the C6 connected at the same strength regardless.

diabetic_debate · January 30, 2026, 12:39am

So 24 hours have passed and I have done tens of OTA updates with LVGL and so far the device has not failed to connect to wifi yet.
