General issue report

Hello @zhangyanjiaoesp . This is a strange sidecase we found in our systems.

v4.4.6-103-g5daf5610b9

Setup

• One hotspot
• One device with WIFI and LTE (for now LTE not necessary). This device has a esp_wifi_set_max_tx_power set to 2dB (8)
• One device with esp_wifi_set_max_tx_power set to 14dB

I currently have the hotspot put next to the device with 14dB. The device with 2dB is put at 8 meters from the phone and the other device.

Powering:

• Enable hotspot
• Enable device with 2dB
• Wait for 2dB device to connect to the hotspot. My device sees -63dB

network {
  mesh_layer: 1
  mesh_p_rssi: -63
  mesh_p_mac: 542
  modem_state: MODEM_ON_AT_READY
  modem_rssi: -200
}

• Switch on device 14dB next to the hotspot (60cm away)

What i see:

• The device starts looping between

Any help? Thanks
